Giant cell tumor of tendon sheath

Case contributed by Dr Maulik S Patel

Presentation

Left hand - AT MCP joint / Proximal phalanx region - Palmer nodule - 5 yrs. Radiograph - Not available.

Patient Data

Age: 35 - 40 yrs
Gender: Male
Modality: Ultrasound

Well-defined ovoid lesion is seen in region of interest. Lesion is at level of 4th Metacarpo-phalangeal joint and proximal phalanx.

Size       - 25 x 21 x 10 mm.  Long axis of lesion  is parallal to metacarpus.

Location - Superficial to flexure tendon of 4th digit. Lesion surrounds about 180 degree of flexure tendon. It is abutting flexur tendon. 

Dynemic scan shows free tendon movement from lesion.

Morphology - Heterogeneously hypoechoic , - Solid - NO calcification / cystic changes.

                 - Small lobulations present. - No posterior acoustic enhancement.

                 - NOt compressible.

 Dopplar     - Flow in predomimently in wall of lesion.- Central flow present.     

 

Case Discussion

On basis of ultrasound findgings and history of slow growth, possibility of giant cell tumor of tendon sheath was suggest.

Lesion was excised.
Histo-pathology - Giant cell tumor of tendon sheath.
