Abstract:
Osteochondromas are the most common benign bone tumors. Vascular complications are unusual, with false arterial aneurysms being the majority among them. Although there are several reports of false aneurysms because of an exostosis in the femoro-popliteal region, cases presenting with a false aneurysm of the brachial artery are quite rare. Many suggestions have been made regarding prevention, diagnosis, and treatment of these false aneurysms, although there are no official guidelines. Therefore, this report aims to present 2 unusual cases of patients with a false aneurysm in the femoral and brachial artery, respectively, because of an exostosis. Literature data are discussed and useful conclusions regarding optimal management are made.

Gross Anatomy of Bone
The diaphysis is the tubular shaft that runs between the proximal and distal ends of the bone. The walls of the diaphysis are composed of dense and hard compact bone made of numerous osteons — the functional unit of the compact bone. The hollow region in the diaphysis is called the medullary cavity, which harbors the bone marrow. In infants and children, this marrow cavity is filled with red marrow, whereas in...
