title: Hemangioma, a rare cause of photopenic lesion on skeletal imaging.
abstract: In searching for disease on skeletal images it is important to identify areas of increased activity and cold lesions, which are usually more difficult to identify. Focal photon-deficient lesions are due to metastatic disease in over 80% of cases. They may occur if the tumor is extremely aggressive, if there is disruption of the blood supply to the bone, or if there is significant marrow involvement, particularly in a vertebral body. Some of the common causes of a photopenic lesion are avascular necrosis, malignant bone tumors such as multiple myeloma, metastasis, radiation therapy, attenuation artifacts such as prosthesis or pacemaker, and early osteomyelitis. A case of hemangioma of the dorsal vertebra, a rare cause of photopenic lesion, is reported here.
