Dissecting Mycotic RCA Aneurysm Detected on 67Ga Scintigraphy.

A 61-year-old man presented with pneumonia and myocardial infarction on a background of diabetes and end-stage renal failure. Methicillin-resistant Staphylococcus aureus bacteremia was confirmed in the setting of ongoing pyrexia. The patient was referred for a 67Ga study, which revealed Ga-avid active disease in the pericardial effusion. This was localized further on CT/MRI and coronary angiography to a dissecting right coronary artery aneurysm, which was treated with surgical repair and long-term antibiotic treatment.
