Simultaneous Triquetrum, Lunate, and Capitate Interosseous Ganglion Cysts

Intraosseous carpus ganglion cysts are very rare causes of hand and wrist pain. Isolated cases of lunate, scaphoid, pisiform, hamate, triquetrum, capitate, metacarpal, and phalanx cysts have no report of more than two carpal cysts, according to our knowledge.

A case of simultaneous triquetrum, lunate, and capitate intraosseous ganglion cysts is presented. A 56-year-old right-handed woman presented with a 6-month history of persistent left-wrist pain. An old minor trauma was reported; however, the plain radiographs did not show any fractures. Subsequently, magnetic resonance imaging was performed, and it showed small cysticstructures in the lunate, triquetrum, and capitate which is keeping with small intraosseous ganglia. The patient did not want to go down the surgical route as the pain was to some extent manageable.

Intraosseous carpal ganglion cysts, although rare, can cause chronic wrist pain and should be included in the differential diagnosis.
