She was admitted to hospital with a 1-week history of unresolving cough, coloured sputum with occasional haemoptysis and fever despite oral antibiotics. Radiology revealed a cavitating right lower lobe lung abscess. After 4 weeks of treatment, follow-up radiology showed incomplete resolution. Bronchoscopy revealed a white, avascular cystic lesion in the right lower lobe and serology testing for <jats:italic>Echinococcus granulosus<\/jats:italic> was positive. Repeat imaging eventually confirmed the cystic lesion with the 'air bubble'sign. A thorough travel history, a high index of clinical suspicion and close follow-up are essential in making a diagnosis of pulmonary cystic echinococcosis.<\/jats:p>","DOI":"10.1136\/bcr-2017-220909","type":"journal-article","created":{"date-parts":[[2017,8,1]],"date-time":"2017-08-01T02:40:17Z","timestamp":1501555217000},"page":"bcr-2017-220909","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":2,"title":["The non-resolving lung cavity: a case of pulmonary cystic echinococcosis"],"prefix":"10.1136","volume":"2017","author":[{"given":"Simon","family":"Mifsud","sequence":"first","affiliation":[{"name":"Department of Medicine, Mater Dei Hospital, Msida, Malta"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Emma Louise","family":"Schembri","sequence":"additional","affiliation":[{"name":"Department of Medicine, Mater Dei Hospital, Msida, Malta"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jonathan","family":"Gauci","sequence":"additional","affiliation":[{"name":"Department of Medicine, Respiratory Division, Mater Dei Hospital, Msida, Malta"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Adrian","family":"Mizzi","sequence":"additional","affiliation":[{"name":"Department of Medical Imaging, Mater Dei Hospital, Msida, Malta"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Charles","family":"Mallia Azzopardi","sequence":"additional","affiliation":[{"name":"Department of Medicine, Infectious Disease Division, Mater Dei Hospital, Msida, Malta"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Josef","family":"Micallef","sequence":"additional","affiliation":[{"name":"Department of Medicine, Respiratory Division, Mater Dei Hospital, Msida, Malta"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2017,7,31]]},"reference":[{"key":"2025082707173162000_2017.jul29_1.bcr-2017-220909.1","doi-asserted-by":"crossref","first-page":"1003","DOI":"10.1007\/s12098-008-0165-8","article-title":"Diagnosis and treatment of pulmonary cystic hydatidosis","volume":"75","author":"Tatar","year":"2008","journal-title":"Indian J Pediatr"},{"key":"2025082707173162000_2017.jul29_1.bcr-2017-220909.2","first-page":"170","article-title":"Pleural effusion obscuring pulmonary echinococcosis: diagnosis by cytology","volume":"2","author":"Jain","year":"2015","journal-title":"Ann Path Lab Med"},{"key":"2025082707173162000_2017.jul29_1.bcr-2017-220909.3","doi-asserted-by":"crossref","first-page":"167","DOI":"10.3109\/2000-1967-078","article-title":"A rare primary location of echinococcal disease: report of a case","volume":"110","author":"Zulfikaroglu","year":"2005","journal-title":"Ups J Med Sci"},{"key":"2025082707173162000_2017.jul29_1.bcr-2017-220909.4","first-page":"1060","article-title":"Mult\u0131ple hydat\u0131d cyst in gluteal reg\u0131on: a case report","volume":"4","author":"\u00d6","year":"2016","journal-title":"Annals of Clinical Pathology"},{"key":"2025082707173162000_2017.jul29_1.bcr-2017-220909.5","doi-asserted-by":"publisher","DOI":"10.1183\/09031936.03.00108403"},{"key":"2025082707173162000_2017.jul29_1.bcr-2017-220909.6","doi-asserted-by":"crossref","first-page":"99","DOI":"10.1016\/S1665-2681(19)32149-0","article-title":"Hepatic Echinococcus granulosus.
