Septic pulmonary infarcts in an IV drug user

Case contributed by Dr Chris O'Donnell


Known IV drug user. Cough and fever with S.aureus cultured in blood. Recent cardiac murmur with tricuspid valve vegetations on echocardography

Patient Data

Age: 25
Gender: Female

Multiple peripherally-located, wedge-shaped mass lesions in the lung, many having central cavitation

Case Discussion

The appearances are typical of infected pulmonary infarcts by way of the clinical history (IVDU)morphology (wedge-shaped), location (peripheral) and central cavitation.  The presence of positive blood cultures confirms the diagnosis and excludes other possibilities including cavitating metatases (eg SCC) and granulomas (eg Wegener).
