Middle lobe syndrome (MLS) as a presentation of this disease is a distinct rarity. A 45-year-old woman, a never-smoker, presented with cough and streaky haemoptysis. Imaging demonstrated a trapezoidal opacity with its base towards the hilum and contiguous with the right cardiac border. The reformatted sagittal view confirmed the diagnosis of MLS. Fibreoptic bronchoscopy (FOB) revealed an avascular white membranous structure wholly occluding the medial segment of the middle lobe. This was completely removed through gentle suction. Bronchial aspirate revealed hooklets of hydatid and echinococcal serology was positive. Subsequently, three cycles of albendazole were administered with remarkable clinical and radiological improvement. To the best of our knowledge, this is the first detailed description of MLS caused by pulmonary hydatidosis that was completely removed through FOB.<\/jats:p>","DOI":"10.1136\/bcr-2016-214670","type":"journal-article","created":{"date-parts":[[2016,4,4]],"date-time":"2016-04-04T10:17:45Z","timestamp":1459765065000},"page":"bcr2016214670","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":5,"title":["Middle
