Tibioperoneal Trunk Aneurysm Resulting in Compartment Syndrome with Associated Aneurysms of the Popliteal and Dorsalis Pedis Arteries.

True aneurysms of the tibioperoneal trunk are rare. Given the scarcity of reports, the clinical presentation and treatment is not well defined. This is a case report of a 50-year-old male patient presenting with severe lower extremity swelling and compartment syndrome with neurological compromise secondary to a tibioperoneal trunk aneurysm.
