Intraspinal extradural cysts communicating with adjacent herniated disks: imaging characteristics and possible pathogenesis.
نویسندگان
چکیده
We report two cases of intraspinal extradural cysts communicating with an adjacent herniated disk that we term "disk cysts." These cysts were well defined and homogeneous, and were present in the ventrolateral extradural space adjacent to a lumbar herniated disk. They had rim enhancement on contrast-enhanced MR images, and communication with a herniated disk was revealed by diskography.

Synovial cysts of the lumbosacral spine: diagnosis by MR imaging.
Intraspinal synovial or ganglion cysts are uncommon lesions associated with degenerative lumbosacral spine disease. CT usually reveals cystic lesions adjacent to a facet joint, and they may show calcification. MR imaging of four surgically confirmed cases of intraspinal synovial cysts revealed subtle signal changes compared with CSF. Short TR/TE images showed the lesions to be slightly hyperint...
متن کاملRecurrent postdiskectomy low back pain: MR-surgical correlation.
The preoperative MR findings in 11 patients, all of whom had developed recurrent low back pain after surgery for herniated lumbar intervertebral disk, were correlated with the surgical findings to determine possible criteria for distinguishing recurrent disk herniation from postoperative scar (extradural fibrosis). The preoperative MR findings agreed with the surgical findings in seven of eight...
متن کاملLumbar intraspinal extradural ganglion cyst.
A case is presented of an intraspinal extradural ganglion cyst at the L4-5 level. The clinical picture suggested a herniated nucleus pulposus at this level. A myelogram revealed a round lesion almost completely obstructing the flow of Pantopaque at the L4-5 level. A ganglion cyst with a haemorrhage into it and the surrounding tissue was removed, and surgery was followed by complete recovery.

Intraspinal extradural spinal cysts are rare lesions, which can induce symptoms due to spinal cord compression or even CSF low pressure syndrome. They are regarded to be result of a trauma, post-surgical, or even congenital. Depended on size and location of the cysts, patients could be asymptomatic for a long time until an enlargement of the cyst. To best of our knowledge, there is no previous ...
متن کاملSpinal extradural arachnoid cysts: clinical, radiological, and surgical features.
Extradural arachnoid cysts in the spine are rare and are seldom a cause of spinal cord compression. They are thought to arise from congenital defects in the dura mater, and they almost always communicate with the intrathecal subarachnoid space through a small defect in the dura. The mainstay of treatment in patients with neurological symptoms is surgical removal of the cyst together with ligati...
