RT Journal Article SR Electronic T1 Coexisting pulmonary haemorrhage and venous thrombosis: a tricky but novel case JF BMJ Case Reports FD BMJ Publishing Group Ltd SP bcr2016217168 DO 10.1136/bcr-2016-217168 VO 2016 A1 Alexandra Fielding A1 Mira Pecheva A1 Aser Farghal A1 Russell Phillips YR 2016 UL http://casereports.bmj.com/content/2016/bcr-2016-217168.abstract AB We present a case of Lemierre's disease complicated by pulmonary artery pseudoaneurysm. A previously well woman aged 43 years presented with a history of a sore throat and worsening dyspnoea. She was diagnosed with a severe cavitating bilateral pneumonia complicated by internal jugular vein thrombosis consistent with a diagnosis of Lemierre's disease. She had an episode of massive haemoptysis which was confirmed to be due to a pulmonary artery pseudoaneurysm which required radiologically guided embolisation. She then required surgical decortication for bilateral empyemata. Blood cultures revealed growth of Slackia exigua, an organism yet to be linked with both of these complications concurrently. We believe this to be a novel case of this bacterium causing thrombosis and haemorrhage.
