Abstract:
Four additional cases of synovial cyst (ganglion) arising from the facet joint between L4 and L5 are reported. Only five such cases have been reported in the past. For the first time impressive and characteristic myelographic findings are described, which make a preoperative diagnosis possible in these cases.
