Bone hemangiomas are benign, malformed vascular lesions, overall constituting less than 1% of all primary bone neoplasms. They occur most frequently in the vertebral column (30-50%) and skull (20%), whereas involvement of other sites (including the long bones, short tubular bones, and ribs) is extremely rare. Bone hemangiomas are usually asymptomatic lesions discovered incidentally on imaging or postmortem examination and mostly encountered in the middle-aged. The symptoms are largely nonspecific and depend on the site, size, and aggressiveness of the tumors.
