Aneurism is a stretch, convexity and sacs in artery which is caused by abnormally congenital connective tissue, infection, arterial inflammation or artery wall trauma. True brachial artery aneurysm is relatively rare. There are only some cases that have been reported previously in medical literature. Brachial artery aneurysm might be asymptomatic or revealed by a brachial mass with beating pulse or peripheral ischemia. The diagnosis usually relies on ultrasound and arterial scan or magnetic resonance imaging (MRI). The main treatment is the surgery which allows cutting the aneurysm and grafted with a part of great saphenous vein by two end-to-end anastomoses. We present a case report of true aneurysm of brachial artery in a 40 years old woman who was treated in Thai Binh Medical University Hospital.
