A variety of cystic lesions may develop in spinal canal. These cysts can be divided into intramedullary, intradural, extradural, cervical, thoracic, lumbar, and sacral cysts according to anatomical presentation, as well as arachnoid, meningeal, perineural, juxtafacet, discal, neurenteric cysts, and cyst-like lesions according to different etiologies. Mechanisms of initiation and growth vary for...
A herniation of the thoracic spinal cord into the mouth of an extradural arachnoid cyst is reported in a 37 year old man. This is the 20th case, but the first posterior herniation; all the others were anterior. He presented with progressive paraparesis and the magnetic resonance imaging (MRI) showed kinking of the cord into the cyst. Surgical release of the neck of the hernia was successful.
Anterior cervical location of arachnoid cyst is a rare and only 22 cases have been reported in the literature. The surgical approach was quite varied and mostly these cysts were accessed via dorsal laminectomy, with few patients developing postoperative neurological deficit. We report a 51-year-old male with a cervical arachnoid cyst extending from the dens to the inferior border of the C3 body...
Traumatic spinal subdural hematoma is a rare entity. Hemorrhage of intracranial arachonoid cyst is also uncommon. One 20 year-old man suffered from subacute intraspinal subdural hematoma in the sacral level after minor sports injury. He received spinal surgery for decompression and the symptoms recovered well after operation. Unfortunately, he suffered from sudden onset of aphasia one week late...
Spinal extradural arachnoid cyst (SEDAC) is a cyst in the spinal canal that protrudes into the epidural space from a defect in the dura mater and leads to neurological disturbances. We previously showed that familial SEDAC is caused by FOXC2 mutation; however, the causal gene of sporadic SEDAC has not been identified. To identify the causal gene of sporadic SEDAC, we performed whole exome seque...
We report the case of a 40-year-old man presenting with focal headache and a bulge at the right parietal bone, diagnosed as an intradiploic arachnoid cyst. The cyst wall included "meningothelial hyperplasia," which is a rare finding. While over 40 cases of intradiploic arachnoid cysts have been reported to date, meningothelial hyperplasia in an intradiploic arachnoid cyst does not appear to hav...
