title: Mycotic aneurysm of the tibioperoneal trunk which precipitated acute compartment syndrome: report of a case.
abstract: Mycotic aneurysms located in the tibioperoneal trunk are extremely rare, with only a few cases reported in the literature. Because of their infrequency and clinical presentations mimicking other etiologies, clinicians generally do not arrive at the diagnosis until the diameter becomes large enough to detect pulsation. We herein report a case of a 52-year-old male with an aneurysm of the tibioperoneal trunk resulting from infective endocarditis. His early clinical presentation was acute compartment syndrome of unknown cause, and a fasciotomy was performed by orthopedists who did not recognize the underlying aneurysm. Later, enhanced computed tomography revealed that an irregularly shaped aneurysm existed in his right tibioperoneal trunk. After the sepsis was controlled with the use of systemic antibiotics, resection of the aneurysm was performed in advance of cardiac surgery. No clinical symptoms due to ischemia were observed without any revascularization. Postoperative computed tomography demonstrated fine enhancement of the peroneal and post-tibial arteries via collaterals.
