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 i
s believed to be the first reported in which the communication was sho
wn by arthrography. Demonstration of such a communication can obviate
the need for further imaging to diagnose the lesion. A review of intra
osseous ganglia of the hand and their treatment is presented.
