Abstract
Sarcomas are rare malignancies of mesenchymal origin. Computed tomographic and magnetic resonance imaging characteristics, as well as histologic findings and epidemiology, of sarcomas of the head and neck are reviewed. The sarcomas discussed include rhabdomyosarcoma, fibrosarcoma, osteosarcoma, chondrosarcoma, malignant fibrous histiocytoma, leiomyosarcoma, alveolar soft part sarcoma, Ewing's sarcoma, and synovial sarcoma. The imaging findings of these entities frequently are nonspecific. Imaging, particularly magnetic resonance imaging, has a major role in defining the extent of these tumors. This is important because complete surgical excision is the preferred method of treatment. Imaging also is useful in planning radiation therapy and determining prognosis.
