title: Thoracic chordoma with unusual radiographic features.
abstract: A case of chordoma involving the thoracic spine (T12) is reported. The plain film findings included lytic obstruction and partial collapse of a single vertebral body. Noncontrast CT and CT following Metrizamide myelography revealed vertebral body destruction with paravertebral and intraspinal soft tissue masses. Unusual findings in the case included a photon deficient area on nuclear medicine corresponding to the lesion and normal vascularity on spinal angiography. We know of no previous report describing chordoma as a "cold" defect on bone scanning.
