title: Giant-cell tumours of bone of the hand and wrist: a review of imaging findings and differential diagnoses.
abstract: Giant-cell tumour of bone (GCTOB) is a benign, locally aggressive, primary bone tumour. Involvement of the distal radius accounts for between 10 and 12% of cases of GCTOB, with the bones of the hand and wrist being rarely affected. GCTOB most commonly affects skeletally mature patients between the ages of 20 and 40 years, with the peak incidence being in the third decade. Women are affected slightly more commonly than men. GCTOB involving the bones of the hand most commonly occurs in a central location, which differs from the usual eccentric location seen in GCTOB at other sites. The radiographic features of GCTOB in the hand and wrist are presented. The role of bone scintigraphy, computed tomography and magnetic resonance imaging is discussed. Evaluation of the postoperative patient is also addressed, including the role of dynamic contrast-enhanced magnetic resonance imaging. A comprehensive review of the potential differential diagnoses that should be considered when GCTOB is suspected in the hand and wrist is also presented.
