Post-traumatic intraosseous ganglion in the fifth metacarpal bone.

A radiologically proven post-traumatic intraosseous ganglion of the fifth metacarpal bone is described. Intraosseous ganglia have been described in the literature with reference to benign cyst-like bone lesions. They appear radiographically, as well circumscribed, juxta-articular, cystic lesions, which contain myxoid fibrous tissue histologically. They occur most frequently in the long bones of the lower limb. Most reported cases of intraosseous ganglia in the hand involve the carpal bones, particularly the lunate and the scaphoid. Most intraosseous ganglia are merely an incidental radiographic finding. Those of the carpal bones have been reported to be a source of pain. The literature concerning post-traumatic intraosseous ganglia is scarce. [ABSTRACT FROM AUTHOR]
