RT Journal Article SR Electronic T1 Pulmonary tuberculosis presenting as post-operative fever of unknown origin JF BMJ Case Reports FD BMJ Publishing Group Ltd SP bcr2016216329 DO 10.1136/bcr-2016-216329 VO 2017 A1 Bogue, Patrick A1 Bolland, Mhairi A1 How, Peter A1 Benziger, Harrison YR 2017 UL http://casereports.bmj.com/content/2017/bcr-2016-216329.abstract AB Post-operative fever is common following emergency surgery. Investigation and management of post-operative fever can be challenging when a clear source of sepsis is not evident or the underlying source of infection is not recognised. We herein report a case of secondary pulmonary tuberculosis presenting as post-operative fever following emergency laparotomy for a perforated duodenal ulcer. This case of tuberculosis was diagnosed on day 41 post-operatively and prior inconclusive results meant that we relied mainly on re-visiting history and examination in order to identify 3 targeted investigations: plain chest X-ray, sputum sample and blood test. Accordingly, the co-management of this complex patient achieved a good outcome.
