Angiomatous Syndromes and Associated Conditions Hamangioendothelioma, Hemangiopericytoma, and Angiosarcoma Biopsy, Treatment, and Prognosis Summary Source Information References Abstract Vascular lesions of bone and soft tissue are relatively common musculoskeletal neoplasms.
Hemangioma is the most frequently encountered angiomatous lesion.
Osseous hemangioma commonly involves the spine and calvaria and often has a characteristic radiographic appearance, with either coarsened trabeculae lying adjacent to the vascular channels or multifocal lytic areas creating a honeycomb pattern. Lymphangioma usually occurs in the neck and axillae of young children as a soft-tissue mass composed of large cavernous spaces and is well evaluated with CT, ultrasound, or MR imaging. Vascular lesions can also diffusely involve both bone and soft tissue in angiomatosis. Imaging is important throughout the evaluation of angiomatous lesions for detection, diagnosis, preoperative assessment, and treatment.
