Ultrasound of Giant Cell Tumor of the Tendon Sheath

In this radiology lecture, we review the ultrasound appearance of giant cell tumor of the tendon sheath!
Key teaching points include:

* AKA tenosynovial giant cell tumor, localized nodular tenosynovitis
* 2nd most common mass of hand & wrist after ganglion cyst
* Most common at volar aspect of first 3 digits. Less commonly at wrist, ankle, foot, knee
* On ultrasound, usually homogeneously hypoechoic with well-defined lobulated margins
* Closely associated with tendon, but will not move with tendon = Arises from tendon sheath, not tendon itself
* May show posterior acoustic enhancement, but internal vascular flow typically present
* Usually benign. Can be locally aggressive, rarely malignant. Tx: Surgical excision
* Fibroma of the tendon sheath has a similar ultrasound appearance and location but is less common. Benign. Tx: Surgical excision
