Giant cell tumor - distal radius

Case contributed by Dr Matt A. Morgan

Presentation

Left wrist pain

Patient Data

Age: 20 years
Gender: Female
X-ray

Left wrist radiographs

A well-defined expansile, eccentric, lucent lesion with internal septation in the radial epiphysis, extending to the metaphysis and abutting the cortex.

X-ray

One year later

The expansile lytic lesion has increased in size and now extends through the entire radius. The lesion has the characteristic appearance of a giant cell tumor but the expansile portion has grown considerably since the prior study and may represent a secondary aneurysmal bone cyst arising in the giant cell tumor.

Case Discussion

On resection this was found to be a giant cell tumor of bone, extending to subchondral region and eroding through the cortex into surrounding soft tissues.
