Abstract

Introduction: Bird fancier’s lung (BFL) is a type of hypersensitivity pneumonitis occurring in response to avian antigens (usually inhaled proteins in bird feathers and droppings). The diagnosis is based on a combination of clinical, radiological, and biopsy characteristics. The present study was planned to highlight the clinico-radiological presentation in cases of BFL.

Material and methods: The present study is a retrospective analysis of cases of bird fancier’s lung diagnosed in a unit of Vallabhbhai Patel Chest Institute over a period of two years, from 2013−2014. The clinico-radiological features of the subjects were analysed. The diagnosis of BFL was made as per criteria laid down by Mark Schuyler and Yvon Cormier.

Results: There were a total of fifteen cases diagnosed with BFL during the study period, comprising twelve females and three males with a mean age of 54.93 ± 14.21 years. All the studied subjects gave significant history of exposure to pigeons and were non-smokers. The period of symptoms prior to presentation varied from one to eight years. The main symptoms on presentation were exertional breathlessness and cough. Radiologically, diffuse centrilobular nodules, ground glassing — diffuse or patchy predominant in upper lobes, fibrosis with or without traction bronchiectasis, honeycombing, and mediastinal lymphadenopathy were seen. Bronchoscopy showed ill-defined granulomas and chronic interstitial inflammation.

Conclusions: BFL can exhibit a wide range of radiological patterns, and a high index of suspicion must be maintained, with particular attention to detailed exposure history in every case of interstitial lung disease.
