Abstract: | Intraspinal synovial cysts were diagnosed in six patients during a 5-year period and retrospectively studied. Plain films of the lumbar spine showed degenerative changes in all patients. Lumbar myelography showed a posterior and lateral defect caused by extradural compression. Using CT without constrast enhancement established the diagnosis in five of the six-patients. in four cases MRI was performed, three before and after injection of gadolinium diethyline-triamine penta-acetic acid )Gd-DTPA). Including the patient with a false negative CT, MRI was positive in all patients. |
