The intraosseous synovial cyst is a benign bone tumor of the osteolytic type; it usually develops in the epiphyses of the long bones. Its location on carp bones is rare. We report here the case of a woman of 34 who consults for wrist pain and for whom the diagnosis of an intraosseux scaphoid synovial cyst has been strongly evoked. Surgical treatment was decided by anterior approach of the Scaphoid, with evacuation and trepanning by anterior approach of the Scaphoid. An anatomopathological study confirmed the diagnosis. The clinical and radiological evolution was favorable. In the literature intraosseous synovial cysts have been rarely reported. Standard radiography and CT allow the diagnosis to be made. Surgical abstention and radiological monitoring are a first alternative in cases with little or no symptoms, presenting a zero or very low fracture risk. In case of surgery, curettage of the cyst and filling with cancellous bone graft taken distal to the distal radius or iliac crest is the main treatment. The prognosis of these cysts is generally favorable and the recurrence remains exceptional.
