Imaging Procedures and Findings

A pedunculated outgrowth from vertebral pedicle is seen protruding into spinal canal and causing severe thecal sac impression. Note that the cortex and medullary cavity of the lesion are continuous with the parent bone.

 

Discussion

An osteochondroma is a cartilage-capped bone outgrowth that may be pedunculated or sessile in appearance. Ninety percent of osteochondromas originate from a long bone close to the metaphysis. The most common locations are around the knee (distal femur and proximal tibia) and the proximal humerus. Both CT and MRI demonstrate the continuity of the cortex and medullary cavity of the osteochondroma with that of the parent bone. Complications of osteochondroma include nerve injury, vascular injury, and bursa formation. A rarer complication is the formation of a pseudoaneurysm adjacent to the exostosis.

 

Final Diagnosis

Osteochondroma (exostosis)
