OBJECTIVE: Extrapulmonary localization of tuberculosis accounts for about 15-20% of cases. Several cases of Mycobacterium tuberculosis with vascular involvement have been described, but only few cases for limb vessels. CASE REPORT: We report the case of a 33-year-old man from Gambia with a symptomatic pseudoaneurysm of the right superficial femoral artery. Total body positron emission tomography/computed tomography with [18F]FDG revealed an active infection. The patient underwent vascular reconstruction with a straight reversed vein graft. Molecular testing for Mycobacterium tuberculosis was non-diagnostic. Cultures of the pseudoaneurysm wall and thrombus removed during surgery grew Mycobacterium tuberculosis. CONCLUSIONS: The diagnosis of vascular tuberculosis infection due to Mycobacterium tuberculosis is a challenge. Epidemiology remains the primary criterion for maintaining a high index of suspicion.

Abstract
OBJECTIVE: Extrapulmonary localization of tuberculosis accounts for about 15-20% of cases. Several cases of Mycobacterium tuberculosis with vascular involvement have been described, but only few cases for limb vessels. CASE REPORT: We report the case of a 33-year-old man from Gambia with a symptomatic pseudoaneurysm of the right superficial femoral artery. Total body positron emission tomography/computed tomography with [18F]FDG revealed an active infection. The patient underwent vascular reconstruction with a straight reversed vein graft. Molecular testing for Mycobacterium tuberculosis was non-diagnostic. Cultures of the pseudoaneurysm wall and thrombus removed during surgery grew Mycobacterium tuberculosis. CONCLUSIONS: The diagnosis of vascular tuberculosis infection due to Mycobacterium tuberculosis is a challenge. Epidemiology remains the primary criterion for maintaining a high index of suspicion.
