Communicating intraosseous ganglion of the lunate.
The authors describe a symptomatic intraosseous ganglion of the lunate communicating directly with the scapholunate joint. The communication was demonstrated by arthrography and computed tomography. This case is believed to be the first reported in which the communication was shown by arthrography. Demonstration of such a communication can obviate the need for further imaging to diagnose the lesion. A review of intraosseous ganglia of the hand and their treatment is presented.
