We describe a case of traumatic pseudoaneurysm of the brachial artery presenting as a soft tissue mass in a patient who was treated for an osteochondroma 3 years earlier. This case demonstrates that radiographic follow-up of large osteochondromas is mandatory and that, in patients with soft tissue masses and a history of osteochondroma, pseudoaneurysms should be included in the differential diagnosis. %K Pseudoaneurysm %K Osteochondroma %K Soft tissue mass %K Brachial artery %U http://link.springer.com/article/10.1007/s10195-010-0116-9
