Infectious endocarditis caused by Rhodococcus equi.

Rhodococcus equi is an unusual cause of infection. Furthermore, this infection also tends to be typically described in immunocompromised patients. This report describes a 25-year-old previously healthy man with infectious endocarditis that was found to have been caused by R equi complicated by a subarachnoid hemorrhage, subdural hematoma, and a superior mesenteric artery aneurysm. The patient was successfully treated with antibiotic therapy, followed by a resection of the superior mesenteric artery aneurysm and a repair of the mitral valve. 2010 The Society of Thoracic Surgeons.
