Figure 10a. What every radiologist should know about idiopathic interstitial pneumonias. (2019) Insights into imaging. (b) Axial chest CT image obtained 2 months later after starting pembrolizumab therapy shows bilateral lower lobe ground-glass and reticular opacities (black arrows), with regions of immediate subpleural sparing (white arrows). Figure 3a. How Do Cytotoxic Lymphocytes Kill Cancer Cells? AIPARDS pattern of pneumonitis in a 57-year-old man undergoing nivolumab therapy for stage IV lung adenocarcinoma. Overall, the incidence of ICI therapyrelated pneumonitis is estimated to be between 3% and 6% (21). Infection, including atypical and fungal causes such as invasive aspergillosis, should also be considered and often can be distinguished by clinical and laboratory findings. However, large-scale head-to-head studies comparing various ICI therapies are lacking. Cryptogenic organizing pneumonia: variety of radiologic findings. 94, No. The introduction of a systematic review of case series and case reports covering 919 patients in China and Korea suggests that while chest radiography is of little diagnostic value in the early stages, in intermediate and advanced stages, features suggestive of covid-19 infection may be seen.23 However, it is unclear in the review how the conclusions regarding chest radiography were reached. This question is for testing whether or not you are a human visitor and to prevent automated spam submissions. We review the mechanism of ICIs, discuss the pathophysiology and clinical presentation of ICI therapyrelated pneumonitis with associated imaging manifestations, and highlight important aspects of treatment and monitoring. Possible causative agents include radiation therapy of the chest, exposure to medications used during chemo-therapy, the inhalation of debris (e.g., animal dander), aspiration, herbicides or fluorocarbons and some systemic diseases. Radiographics. 25 (3): 789-801. (c) Follow-up axial chest CT image obtained 2 months later after steroid therapy shows resolved right lower lobe pneumonitis. Recurrent pneumonitis pattern, location of involvement, and severity may vary compared with those at initial presentation. 8. Isr. 1998;171 (3): 835, 838-9. Terhalle E, Gnther G. 'Tree-in-Bud': Thinking beyond Infectious Causes. (a) Baseline axial chest CT image shows a medial left lower lobe lung mass with surrounding ground-glass halo sign (arrow), a finding corresponding to adenocarcinoma. Adjacent bronchial wall thickening is also frequently depicted (Fig 7). 1. Radiation recall pneumonitis in a 65-year-old woman with metastatic breast cancer. (b) Axial chest CT image obtained 2 months after initiating trastuzumab therapy shows a focal region of ground-glass opacities within the posterior and medial left lower lobe (arrow), with a well-defined linear demarcation from the adjacent normal lung. J. Going forward, given the potential complexity of diagnosis and management of ICI therapyrelated pneumonitis, radiologists must work in conjunction with a broader multidisciplinary team to provide optimal care for these patients. (b) Follow-up axial CT image obtained 4 months later after administering nivolumab therapy shows multiple predominantly peripheral and subpleural airspace consolidative opacities (arrows), findings consistent with an OP pneumonitis pattern. Immunotherapy was subsequently held, and steroid therapy was administered. "Faculty of Radiologists . Grainger & Allison's Diagnostic Radiology, Single Best Answer Mcqs. Although not yet incorporated in official immunotherapy response criteria, the combination of anatomic and functional imaging such as fluorine 18 fluorodeoxyglucose (18F-FDG) PET/CT or diffusion-weighted imaging with MRI may be beneficial in predicting treatment response in patients receiving ICI therapy (13,14). COVID-19 rapid guideline: managing suspected or confirmed pneumonia in adults in the community 2020. 5. The main differential diagnosis is infection, which does not respect the boundaries and occurs outside of the prior radiation field. ICI therapyrelated pneumonitis is an irAE, potentially resulting in significant morbidity with possible discontinuation of therapy and possible mortality. Escuissato DL, Ferreira RG, Barros JA, Marchiori E. Pulmonary talcosis caused by intravenous methadone injection. A baseline coronal chest CT image obtained before starting immunotherapy (not shown) showed no airspace abnormalities. The appearance and treatment of OP pattern ICI therapyrelated pneumonitis are virtually indistinguishable from those of cryptogenic OP, although the latter is usually a long-standing process without a temporal relationship to the immunotherapy course. A wide variety of infectious as well as noninfectious causes may result in a similar histologic pattern. Check for errors and try again.

(c) Follow-up axial chest CT image obtained 3 months later after withholding ICI therapy and administering steroid therapy shows resolved pneumonitis. In the last decade, the introduction of immunotherapy has revolutionized the management and treatment approaches for a number of malignancies. [8], Corticosteroid dose and treatment duration vary from case to case. Tree-in-bud signor pattern describes the CT appearance of multiple areas of centrilobular nodules with a linear branching pattern. Some degree of pulmonary fibrosis may be evident in a CT which is indicative of chronic pulmonary inflammatory processes. Respiratory abnormality: HP:0002088: Abnormal lung morphology: Any structural anomaly of the lung. Consider pulmonary emboli as a cause of respiratory symptoms as evidence suggests a high prevalence of thrombotic complications in covid-19 patients in intensive care. When lung markings are partially obscured by the increased whiteness, a ground glass pattern (ground glass opacity, fig 1) occurs. After pneumonitis resolution, clinicians are faced with the decision of whether to restart ICI therapy (ie, rechallenge). Combinations of PD-1 and CTLA-4 inhibitors with nivolumab and ipilimumab have also demonstrated higher irAE rates compared with those of respective monotherapies in patients with advanced melanoma (20). Many of these adverse events are unique from those previously observed with conventional chemotherapy regimens. In cases where both lungs are extensively involved (e.g. ICIs ultimately act by inhibiting the signal pathways responsible for the suppression of T-cellmediated tumor destruction. Although generally considered separate from ICI therapyrelated pneumonitis, sarcoidlike reaction is another potential pulmonary irAE reported with ICI therapy. On CXR bilateral adenopathy and coarse reticular opacities are seen. Reference article, Radiopaedia.org (Accessed on 11 Dec 2022) https://doi.org/10.53347/rID-5223. (b) Axial chest CT image obtained 2 months later after starting pembrolizumab therapy shows bilateral lower lobe ground-glass and reticular opacities (black arrows), with regions of immediate subpleural sparing (white arrows). [6] Patients that are immunodeficient and don't get treated immediately for any type of respiratory infection may lead to more severe infections and/or death. Six weeks after starting nivolumab therapy, the patient presented with severely worsening dyspnea. The presence of bronchocentric lymphohistiocytic interstitial pneumonia with chronic bronchiolitis and non-necrotising granulomas coincides with pneumonitis.[12]. Consolidation is also seen in the periphery of the left upper and mid zones (outlined arrows). (a) Baseline axial chest CT image shows the lungs before starting immunotherapy. Conventional chemotherapy agents have demonstrated a dose-dependent risk of pneumonitis, while overall this has not been shown with ICI therapy (45,46). Bronchiolitis pattern of pneumonitis in a 63-year-old woman undergoing nivolumab therapy for lung adenocarcinoma. 10. (b) Axial chest CT image obtained 2 months later after starting pembrolizumab therapy shows bilateral lower lobe ground-glass and reticular opacities (black arrows), with regions of immediate subpleural sparing (white arrows). Six weeks after starting nivolumab therapy, the patient presented with severely worsening dyspnea. Lee KS, Kullnig P, Hartman TE et-al. 89, No. Pneumonitis describes general inflammation of lung tissue. Causes of bacterial community acquired pneumonias include Streptococcus pneumoniae, Haemophilus influenzae, and Klebsiella20 (not an exclusive list). (c) AP chest radiograph of patient C on day 10 of admission, showing progression to severe covid-19 pneumonia: patient intubated with endotracheal tube, central lines, and nasogastric tube in situ. Pneumonitis can be separated into several distinct categories based upon causative agent. Tree-in-bud pattern. Described findings of HP pattern mirror those typically found in cases of subacute HP depicted in other settings. Kim SJ, Lee KS, Ryu YH et-al. Figure 10b. Vicky T. Nguyen, Elaine S.

Tree-in-bud sign or pattern describes the CT appearance of multiple areas of centrilobular nodules with a linear branching pattern. Pulmonary nodules may also be depicted, typically in a peribronchovascular distribution and more commonly as smaller nodules (<10 mm). Of 1099 patients 975 had computed tomography but it is unclear how many of the chest radiographs were false negatives for covid pneumonia. We dedicate this manuscript to honour the legacy of our dear co-author and friend Isabelle Tillie-Leblond (19652013), for her outstanding contribution to respiratory disease care and research, and her unconditional friendship.

Usual interstitial pneumonia (UIP) is a histopathologic and radiologic pattern of interstitial lung disease, which is the hallmark pattern for idiopathic pulmonary fibrosis (IPF).. On imaging, usual interstitial pneumonia usually presents with a lung volume loss and an apicobasal gradient of peripheral septal thickening, bronchiectasis, and honeycombing. British Thoracic Society. 218, No. Bronchiolitis pattern of pneumonitis in a 63-year-old woman undergoing nivolumab therapy for lung adenocarcinoma. Prop 30 is supported by a coalition including CalFire Firefighters, the American Lung Association, environmental organizations, electrical workers and businesses that want to improve Californias air quality by fighting and preventing wildfires and reducing air pollution from vehicles. 13. Case 1: Cryptogenic organizing pneumonia. During the process of T-cell activation, various inhibitor receptors also become upregulated, acting as immune checkpoints to limit the overstimulation of the immune response (3). (c) Axial chest CT image obtained 5 months after discontinuation of therapy shows minimal residual (although markedly improved) pneumonitis (arrow) in the left lower lobe. NHS England.

As a result of their input we have made several changes to the manuscript, including adding a clearer explanation of the differing approaches to imaging in the US, UK, and China, and including a reference to emerging information on cardiac complications of covid-19. [1][2] Possible causative agents include radiation therapy of the chest,[3] exposure to medications used during chemo-therapy, the inhalation of debris (e.g., animal dander), aspiration, herbicides or fluorocarbons and some systemic diseases. (c) Follow-up axial chest CT image obtained 3 months later after withholding ICI therapy and administering steroid therapy shows resolved pneumonitis. Make a note of known comorbidities and smoking history on paperwork requesting investigations; this will help radiologists to consider other pathologies that may be causing patients symptoms. The left lower lobe mass also increased in size (white arrow). Treatment is often effective, although recurrence is possible. Two critical pathways for ICIs are the CTLA-4 and PD-1 pathways, which normally function to attenuate T-cell response and action (Fig 1) (5,6). These are longer (at least 2cm and up to 6cm) unbranching lines coursing diagonally from the hila out to the periphery of the lungs. 2006;28 (2): 422-46. However, conventional imaging response criteria such as RECIST 1.1 have shortcomings in the evaluation of treatment response for ICI therapy, leading to the potential for premature cessation of therapy in patients who might otherwise show benefit with therapy (9). [7][12], Reticular or linear patterns may be observed in diagnostic imaging. less than ~2 months) of breathlessness, non-productive cough, weight loss, malaise and fever. Look for cardiac outline abnormalities on chest radiography as cardiac complications are reported with covid-19 (which can be seen on echo15); however, no reports of cardiac abnormalities seen on chest radiographs have been published. (b) Axial chest CT image obtained 4 months later after nivolumab therapy shows multifocal peripheral and subpleural mid- and lower-lung airspace consolidations (arrows), a finding consistent with an OP pattern of pneumonitis. Several key differences in the response patterns of ICI therapeutic agents compared with those of cytotoxic agents include the potential initial transient worsening of disease burden, either through lesion enlargement or the appearance of new lesions (ie, pseudoprogression), and delayed time to treatment response (10). Corticosteroids have been widely used and most patients recover completely 3-4. As with the NSIP pattern, changes of chronic HP including upper lobe fibrosis, volume loss, and traction bronchiectasis have not been reported with ICI therapyrelated pneumonitis. adenocarcinoma in situ or minimally invasive, acute unilateral airspace opacification (differential), acute bilateral airspace opacification (differential), acute airspace opacification with lymphadenopathy (differential), chronic unilateral airspace opacification (differential), chronic bilateral airspace opacification (differential), osteophyte induced adjacent pulmonary atelectasis and fibrosis, pediatric chest x-ray in the exam setting, normal chest x-ray appearance of the diaphragm, posterior tracheal stripe/tracheo-esophageal stripe, obliteration of the retrosternal airspace, Anti-Jo-1 antibody-positive interstitial lung disease, leflunomide-induced acute interstitial pneumonia, fibrotic non-specific interstitial pneumonia, cellular non-specific interstitial pneumonia, respiratory bronchiolitisassociated interstitial lung disease, diagnostic HRCT criteria for UIP pattern - ATS/ERS/JRS/ALAT (2011), diagnostic HRCT criteria for UIP pattern - Fleischner society guideline (2018), domestically acquired particulate lung disease, lepidic predominant adenocarcinoma (formerly non-mucinous BAC), micropapillary predominant adenocarcinoma, invasive mucinous adenocarcinoma (formerly mucinous BAC), lung cancer associated with cystic airspaces, primary sarcomatoid carcinoma of the lung, large cell neuroendocrine cell carcinoma of the lung, squamous cell carcinoma in situ (CIS) of lung, minimally invasive adenocarcinoma of the lung, diffuse idiopathic pulmonary neuroendocrine cell hyperplasia (DIPNECH), calcifying fibrous pseudotumor of the lung, IASLC (International Association for the Study of Lung Cancer) 8th edition (current), IASLC (International Association for the Study of Lung Cancer) 7th edition (superseeded), 1996 AJCC-UICC Regional Lymph Node Classification for Lung Cancer Staging, Bronchiolitis obliterans organizing pneumonia (BOOP), Bronchiolitis obliterans organising pneumonia (BOOP), Bronchiolitis obliterans with organizing pneumonia (BOOP), Bronchiolitis obliterans with organising pneumonia (BOOP), unilateral or bilateral patchy areas (commonest finding, usually peripheral, subpleural, peribronchovascular, may be numerous in immunocompromised patients, patchy consolidation with a predominantly subpleural and/or peribronchial distribution, small, ill-defined peribronchial or peribronchiolar nodules, a perilobular pattern with ill-defined linear opacities that are thicker than the. (a) Baseline axial chest CT image shows the lungs before starting immunotherapy. Cordier JF. Respir. JP used his knowledge of assessment and management of covid-19 patients to inform the article. This page was last edited on 16 October 2022, at 13:44. Patients with grades 3 and 4 pneumonitis require permanent discontinuation of ICI therapy and more intensive care, requiring inpatient admission with close monitoring. AJR Am J Roentgenol. Although not specifically addressed in published guidelines given the potential for high steroid doses administered for extended periods, infectious prophylaxis may be warranted. Table 3: ICI Therapyrelated Pneumonitis Patterns. (c) Axial CT image in a 57-year-old man undergoing imatinib therapy for metastatic gastrointestinal stromal tumor shows small patchy peripheral ground-glass opacities (arrows) in the bilateral lower lobes. 9. JC used her expertise as a chest radiologist, seeing approximately 200 images of suspected covid-19 to inform this article. 4, Journal for ImmunoTherapy of Cancer, Vol. Enter your email address below and we will send you the reset instructions. ICIs target the cell surface receptors cytotoxic T-lymphocyte antigen-4, programmed cell death protein 1, or programmed cell death ligand 1, which result in immune systemmediated destruction of tumor cells. Respiration. 7. Several distinct radiographic patterns of pneumonitis have been observed: (a) organizing pneumonia, (b) nonspecific interstitial pneumonia, (c) hypersensitivity pneumonitis, (d) acute interstitial pneumoniaacute respiratory distress syndrome, (e) bronchiolitis, and (f) radiation recall pneumonitis. 58, No. Scleroderma is a rare connective tissue disorder with unknown and complex pathogenesis. The mechanism of radiation recall reactions remains unclear, although possibilities include changes in the function of stem cells in the irradiated field versus idiosyncratic drug hypersensitivity reactions (39). It is named because this sign resembles a reverse S shape, and is therefore sometimes referred to as the reverse S-sign of Golden.. Figure 5a. Although typically seen with right upper lobe collapse, the S-sign can also be seen with the collapse of other lobes.It is created by a central mass obstructing the upper 8. (oxford).
