Wrist pain due to occult dorsal carpal ganglion.

Six patients with chronic wrist pain were diagnosed with occult dorsal carpal ganglion using sonogram despite the absence of a palpable mass. The four females and two males were aged 19-26 years. Symptoms had been present for an average of 17 months. Tenderness in the scapholunate fossa and pain at the wrist with motion were constant findings. Each was treated with ganglion puncture and the pain was relieved in all six patients and no recurrence was noted at follow up of at least 6 months.
