A 28-year-old man presented to our hospital with heaviness of the left chest for the past 10\u2005days, which was preceded by a sudden, short stabbing pain in the left chest after straining. Chest X-ray revealed left-sided hydropneumothorax. A peripheral blood picture revealed significant eosinophilia. A pleural fluid report also showed eosinophilia and a few motile microfilaria of <jats:italic>Wuchereria bancrofti<\/jats:italic>. Microfilaria was also documented in peripheral blood. There was no evidence of other organ system involvement. The patient was diagnosed with \u2018Filarial Hydropneumothorax\u2019. After treatment with a temporary chest drain and oral diethylcarbamazine citrate, there was dramatic relief of symptoms and radiological improvement. The patient has been symptom free with no features of recurrence through 8\u2005months of follow-up.<\/jats:p>","DOI":"10.1136\/bcr-2015-209470","type":"journal-article","created":{"date-parts":[[2015,11,24]],"date-time":"2015-11-24T11:42:46Z","timestamp":1448365366000},"page":"bcr2015209470","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":3,"title":["Filarial hydropneumothorax: a strange journey"],"prefix":"10.1136","volume":"2015","author":[{"given":"Arkaprabha","family":"Chakraborty","sequence":"first","affiliation":[{"name":"Department of General Medicine, Medical College Kolkata, Kolkata, West Bengal, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anindya","family":"Mukherjee","sequence":"additional","affiliation":[{"name":"Department of General Medicine, Medical College Kolkata, Kolkata, West Bengal, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Payel","family":"Talukdar","sequence":"additional","affiliation":[{"name":"Department of Psychiatry, NRS Medical College, Kolkata, West Bengal, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Arunansu","family":"Talukdar","sequence":"additional","affiliation":[{"name":"Department of General Medicine, Medical College Kolkata, Kolkata, West Bengal, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2015,11,24]]},"reference":[{"key":"2025082803555766000_2015.nov24_1.bcr2015209470.1","doi-asserted-by":"publisher","DOI":"10.4103\/0022-3859.68650"},{"key":"2025082803555766000_2015.nov24_1.bcr2015209470.2","doi-asserted-by":"publisher","DOI":"10.1016\/0277-9536(95)00288-X"},{"key":"2025082803555766000_2015.nov24_1.bcr2015209470.3","doi-asserted-by":"publisher","DOI":"10.4103\/0970-1591.19551"},{"key":"2025082803555766000_2015.nov24_1.bcr2015209470.4","doi-asserted-by":"crossref","first-page":"119","DOI":"10.3347\/kjp.2008.46.3.119","article-title":"Clinical and pathological aspects of filarial lymphedema and its management","volume":"46","author":"Shenoy","year":"2008","journal-title":"Korean J Parasitol"},{"key":"2025082803555766000_2015.nov24_1.bcr2015209470.5","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0002874"},{"key":"2025082803555766000_2015.nov24_1.bcr2015209470.6","doi-asserted-by":"publisher","DOI":"10.1590\/S0100-879X1999001200003"},{"key":"2025082803555766000_2015.nov24_1.bcr2015209470.7","first-page":"1","article-title":"Lymphatic filariasis: the disease and its control.
