Listen Later

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
