Imaging in a case of giant cell tumor of tendon sheath in foot: A case report with review of literature

Large sized Giant cell tumors (GCT) of the tendon sheaths of the foot are rare. We present a case with a large tumor over the dorsum of foot which was diagnosed and studied by plain radiography, Ultrasound, CT and MRI scans. It was histologically confirmed on biopsy. When the size of the tumor (like Giant cell tumor) is too large and spread over multiple bones of the foot MRI is the imaging modality of choice to precisely define the anatomy to help in taking surgical decisions
