[Atypical ganglion cysts].
Intra- or para-articular ganglion cysts are frequent and can develop at some distance from the joints. The authors describe examples of typical and atypical ganglion cysts, namely meniscal cyst, intra-articular cyst, intraosseous cyst, intraneural cyst of tibial nerve, adventitial cyst of popliteal artery, and para-articular cyst of the hip, filled with gas of presumed articular origin. The diagnosis of a ganglion cyst can be difficult when there is no evident articular communication. If demonstration of communication is necessary (in case of uncertain diagnosis or for preoperative assessment), the best procedure is arthrography followed by a CT scan 1-2 hours after the injection.
