[Skeletal hemangiomas]

Abstract

Hemangiomas are benign tumors, which are mainly composed of neoplastic blood vessels. The exact pathogenesis is still unclear. They are the most common benign spinal tumors and also occur less commonly in the bones of the extremities. Hemangiomas are often clinically asymptomatic and are diagnosed as incidental findings. Women are affected more frequently than men (2:1). The X‑ray and computed tomography (CT) diagnostics typically demonstrate the classical honeycombing or vertically orientated lucencies separated by thickened cancellous bone in the affected skeletal section. Vertebral hemangiomas are hyperintense in both T1 and T2-weighted magnetic resonance imaging (MRI). The treatment of vertebral hemangiomas ranges from irradiation, embolization and vertebroplasty to operative decompression, resection of the tumor and instrumented stabilization. In the long bones intralesional curettage and bone grafting with additive osteosynthesis is the main treatment modality. The prognosis for osseous hemangiomas is good.
