was distinguished from tracheobronchitis principally by bilateral changes on chest radiograph that appeared 1-3 weeks after onset of symptoms (DeNardi et al.
and pulmonary fibrosis in non-smal-cell lung cancer: Pulmonary function, prediction, and prevention.
Several authors previously described bronchiolocentric fibroinflammatory changes, such as idiopathic bronchiolocentric interstitial pneumonia, centrilobular fibrosis, airwaycentered interstitial fibrosis, peribronchiolar metaplasia, and bronchiolitis interstitial pneumonitis
. (64-68) These patterns seem to belong to the same spectrum but differ in detail in each series.
(2015), most of the radiation pneumonitis
experienced by SABR patients is RTOG grade 1 or 2 and mostly asymptomatic, with less than 8% of patients experiencing grade 2 or greater radiation pneumonitis
requiring intervention .
He was empirically treated with methylprednisolone and piperacillin/tazobactam for possible pneumonitis
These are limited to bronchiectasis, eosinophilic pneumonia, pleural effusion, and suspected hypersensitivity pneumonitis
Several cases of lupus pneumonitis
mimicking pneumonia are reported in the pediatric medical literature [12-14].
Our patient developed Grade 4 pneumonitis
6 weeks after nivolumab treatment, and the radiographic pattern was AIP/ARDS.
Due to the transbronchial biopsy findings, combined with the recent initiation of ustekinumab, the patient was diagnosed with ustekinumab-induced hypersensitivity pneumonitis
. He was treated with cessation of the biological therapy, topical emollients and topical steroids for eczema.
In retrospective study of 63 patients with SLE Boulware and Hedgperth, looking for interstitial pneumonitis
found 16 patients (25.4%) with ILD.
. Pediatrics 1974;54(3):351-357.
The American Thoracic Society/European Respiratory Society Statement on Update of the International Multidisciplinary Classification of the Idiopathic Interstitial Pneumonias 2013 was used in the diagnosis and classification of ILD.11 Interstitial lung diseases were classified into different categories including IPF, non-specific interstitial pneumonitis
(NSIP), hypersensitivity pneumonitis
(HP), cryptogenic organising pneumonia (COP), sarcoidosis, connective tissue disease-associated interstitial lung disease (CTD-ILD) and other rare interstitial lung diseases depending upon the patient's clinical presentation, laboratory investigations, lung function tests, environmental exposures, radiological findings and pathological diagnosis if available.
