Abnormal signal infiltrative enhancing mass lesion measuring about 20 x 25 mm lateral to the carpal tunnel and flexor tendons with cortical remodeling and extension to the radius styloid.
Another similar, smaller lesion measuring about 8 x 27 mm at the medial wrist with erosion at the triquetrum.
From the case:
Tenosynovial giant cell tumor - wrist
{"current_user":null,"step_through_annotations":true,"access":{"can_edit":false,"can_download":true,"can_toggle_annotations":true,"can_feature":false,"can_examine_pipeline_reports":false,"can_pin":false},"extraPropsURL":"/studies/142577/annotated_viewer_json?c=1699255385\u0026lang=us"}
The larger mass had been biopsied, and histopathologic examinations were compatible with a giant cell tumor of the tendon sheath.
Case Discussion
Tenosynovial giant cell tumors are typically benign and originate from the synovium of joints, bursae, or tendon sheaths, exhibiting synovial differentiation.
