Abstract

Ganglia are common and usually occur in close relationship to joints, tendon sheaths or tendons. In spite of their frequency, involvement of bone has been considered as very rare. This concept has changed after the report by Fisk of the intraosseous penetration of a periosteal ganglion like structure with formation of a cystic defect in the subjacent bone, but case reports have most often dealt with the lower extremity, with a much less frequent occurence reported within the carpal bones. A carpal intraosseous ganglion is a rare phenomenon that presents as a painful wrist associated with mild swelling, the symptoms are often exacerbated by gripping. Plain X-ray films usually reveal a well defined round or oval radioluscent defect enclosed by sclerotic rim. Computed tomography and magnetic resonance imaging help clearify the extent of the abnormality and allow for more accurate preoperative planning. The etiology of this lesions is unclear but may be related to the localized vascular disturbance or a penetrating extraosseous ganglion. We have recently encountered a 45 years female patient who had cystic osseous lesion in scaphoid which is best desiginated intraosseous ganglion. So we report a case of our experience.
