Mycotic aneurysm of the tibioperoneal trunk: a first manifestation of an infected endocarditis

infrapopliteal mycotic aneurysm resulting from endocarditis is rare, with only a few reported cases. we describe the case of a 28-year-old male patient who was suffering with pain and edema in the right leg. the ultrasound revealed an aneurysm of the right tibioperoneal trunk and a deep vein thrombosis (dvt). the patient was admitted and developed acute congestive heart failure, being diagnosed with possible endocarditis. a pseudo-aneurysm was revealed by arteriography. aggressive antibiotic treatment was initiated, and open surgery confirmed a mycotic pseudo-aneurysm of the tibioperoneal trunk. to our knowledge, this is the 8th case reported of an infected aneurysm in this particular location.
