Rare spindle cell hemangioma of bone: Case report and literature review.

Spindle cell hemangioma is a rare benign hemangioma. It is mainly found as small soft tissue nodules in the distal extremities, especially in the hands. The manifestation in bone is extremely rare. We present a case of spindle cell hemangioma of bone in the frontal bone. We also reviewed the literature to find the common imaging findings of intraosseous hamangiomas. The main manifestations of X-ray and CT were osteolytic lesions with soap bubble-like changes, and soft tissue mass formation. Magnetic resonance imaging mainly showed a lobulated mass with clear boundary, uneven hyperintense on T2WI, and obvious enhancement on contrast-enhanced scan. Surgical excision is curative. While this lesion is rare, it can be considered in the differential diagnosis if the characteristic imaging features are present.
