In comparison with soft tissue ganglia, the intraosseous ganglion is relatively rare. Although cases of intraosseous ganglia were described in the literature, their occurrence in the carpal bones is indeed rare. We have encountered a patient with an intraosseous ganglion of the scaphoid bone of the wrist.A 63-year-old woman complained of some pain in her left wrist. There was limitation of motion but not inoammition. Roentgenographic study demonstrated a round-to-oval, radio lucent cystic lesion in the scaphid bone of the wrist. Operation was carried out for the purpose of both diagnosis and treatment. The scaphoid bone consisted of yellow fibrous cystic material, and this was removed and curettaged of the cavity, and then the defect was packed with banked bone. Histologically the wall of the cyst is composed of fibrous tissue without lining cells, and we finally made a diagnosis of intrasseous ganglion.
