Spontaneous tibioperoneal trunk and anterior tibial artery pseudoaneurysms.

Aneurysms of the tibioperoneal trunk and anterior tibial artery are extremely rare. There are only a few case reports of this entity, for which the majority are secondary to prior trauma or bacteremia and endocarditis. We describe a case of spontaneous pseudoaneurysms of the right anterior tibial artery and tibioperoneal trunk. The pseudoaneurysms were thrombosed on follow-up computed tomography angiography and the patient has been asymptomatic. The patient is being treated conservatively and remains asymptomatic at 1 year of follow-up.
