His chest X-ray was clear and subsequent CT scanning demonstrated multilobar, patchy consolidation and ground glass change in the lung parenchyma. His CD4 count was 864\u2005cells\/mm<jats:sup>3<\/jats:sup> (n=500\u20131500\u2005cells\/mm<jats:sup>3<\/jats:sup>) and viral load 863\u2005IU\/mL. Our primary diagnosis was an atypical pneumonia with associated bronchospasm. The differential diagnosis also included a methamphetamine-induced pulmonary haemorrhage, given the multiple small foci of ground glass change. The patient's sputum cultured <jats:italic>Haemophilus influenzae<\/jats:italic>, which was somewhat surprising, given his unusual CT findings. He recovered with antibiotic therapy and a follow-up CT scan at 6\u2005weeks revealed complete resolution of the radiological findings.<\/jats:p>","DOI":"10.1136\/bcr-2015-209911","type":"journal-article","created":{"date-parts":[[2015,7,6]],"date-time":"2015-07-06T08:14:48Z","timestamp":1436170488000},"page":"bcr2015209911","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["An atypical presentation of a typical pulmonary pathogen in an immunosuppressed patient"],"prefix":"10.1136","volume":"2015","author":[{"given":"Lara Emily","family":"Ulrich","sequence":"first","affiliation":[{"name":"Kingston Hospital, London, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Parthipan","family":"Sivakumar","sequence":"additional","affiliation":[{"name":"Kingston Hospital, London, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2015,7,6]]},"reference":[{"key":"2025082802531062000_2015.jul06_1.bcr2015209911.1","doi-asserted-by":"publisher","DOI":"10.1016\/j.rmr.2012.06.003"},{"key":"2025082802531062000_2015.jul06_1.bcr2015209911.2","first-page":"201","article-title":"Bacterial community-acquired pneumonia in HIV infected patients","volume":"16","author":"Madeddu","year":"2010","journal-title":"Curr Opin Pulm Med"},{"key":"2025082802531062000_2015.jul06_1.bcr2015209911.3","doi-asserted-by":"publisher","DOI":"10.1097\/00063198-200405000-00007"},{"key":"2025082802531062000_2015.jul06_1.bcr2015209911.4","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejrad.2004.03.008"},{"key":"2025082802531062000_2015.jul06_1.bcr2015209911.5","doi-asserted-by":"publisher","DOI":"10.1164\/rccm.201005-0694OC"},{"key":"2025082802531062000_2015.jul06_1.bcr2015209911.6","doi-asserted-by":"publisher","DOI":"10.1148\/radiographics.22.suppl_1.g02oc01s119"},{"key":"2025082802531062000_2015.jul06_1.bcr2015209911.7","doi-asserted-by":"publisher","DOI":"10.1097\/01.rti.0000213567.86408.19"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2015-209911","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,28]],"date-time":"2025-08-28T09:53:17Z","timestamp":1756374797000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2015-209911"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2015,7,6]]},"references-count":7,"alternative-id":["10.1136\/bcr-2015-209911"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2015-209911","relation":{},"ISSN":["1757-790X"],"issn-type":[{"type":"electronic","value":"1757-790X"}],"subject":[],"published":{"date-parts":[[2015,7,6]]}}}
