Intraosseous Ganglion Cyst of Scaphoid: An Uncommon Cause of Radial Wrist Pain

Intraosseous ganglion cyst is a rare bone tumor and the lesion could often be missed. The diagnosis could be delayed so proper radiologic investigation and index of suspicion is necessary .Differential diagnoses of painful cystic radiolucent carpal lesion are osteoid osteoma, osteoblastoma and intraosseous ganglion. Curettage of the scaphoid lesion and filling of void with bone graft provides good functional outcomes. The cyst contains mucoid viscous material without epithelial or synovial lining. We present a case of 30 years old male with intraosseous ganglion cyst of scaphoid which was treated with curettage and bone grafting. Rarely ganglion cyst is found in small bones of hand and should be considered as differential diagnosis of chronic radial wrist pain.

SYNOVIAL FRINGE (PLICA) OF SCAPHO-TRAPEZIAL JOINT FOLLOWING TRAUMA

We herein present a case of radial wrist pain following trauma. Magnetic resonance imaging showed a large area of abnormal soft tissue in the scapho-trapezial joint. The patient was treated successfully by complete resection of the soft tissue. The soft tissue was diagnosed to be synovial fringe based on a histological study. Synovial fringe is frequently reported as a cause of knee and elbow pain, however, it is a rare cause of wrist pain at the scapho-trapezial joint.

AN ANOMALOUS MUSCLE MIMICKING A DORSO-RADIAL GANGLION AS A CAUSE OF RADIAL WRIST PAIN

We report an abnormal muscle on the radial aspect of the wrist, which presented clinically as a ganglion and radial wrist pain. Existence of muscles in the first compartment has been accounted earlier, however its atypical presentation advocates its inclusion in the differential diagnosis of a dorso-radial ganglion and wrist pain.
