Craniospinal intradural arachnoid cyst

Abstract

Summary:A patient with an uncommonly situated congenital intradural arachnoid cyst is reported. The cyst extended from the cervical spinal canal into the posterior cranial fossa and was posterolateral to the spinal cord. The patient's initial complaint was urinary hesitancy. The location ofthe cyst is unique and the presenting complaint rare.

Evolving magnetic resonance spinal cord trauma in child: from hemorrhage to intradural arachnoid cyst

“…2 The treatment of choice of spinal arachnoid cysts is surgical removal of as much of its wall as is safe or shunting procedures. 5,6,11 The general postoperative outcome for these procedures is good recovery in 87% of patients, and severe disability in 11%. 9 In the present case the authors had the opportunity to observe the evolution from hemorrhage as causative of arachnoid adhesions to arachnoid cyst with hypertensive characteristics dislodging spinal cord anteriorly.…”

“…9 However, they may be laterally situated in the dentate ligament. 6,10 Intradural arachnoid cysts are more frequently located in the thoracic spine (70%) or thoracolumbar (12%), but they can also be lumbosacral (13%) and cervical (3%), 6,11 and seldom produce bony changes in the spinal canal. 3 Spinal arachnoid cysts may occur at any age, but are most common in the second decade, and are more common in males by almost twofold.…”

“…Urinary complaints as initial symptoms are rare. 3,5,6,11 The clinical course is usually protracted, mimicking multiple sclerosis in some patients. 2 In acquired arachnoid cystic meningitis, trauma and hemorrhage are considered to be causative or contributing factors, it being postulated that the proliferation of arachnoid trabeculae occurs from the septum posticum for the posteriorly-situated arachnoid cyst.…”

“…1 ± 5 Previous spinal surgery, hemorrhage, in¯ammation and closed spinal trauma with hemorrhage have been suspected as causative of arachnoid cysts or diverticula of the spinal cord. 2,6,7 Interestingly, no spinal arachnoid cysts have been reported in patients after subarachnoid hemorrhage or meningitis, conditions expected to cause arachnoid scarring. 8 Magnetic resonance (MR) of the spine is considered the best diagnostic procedure, showing the real anatomy of the cyst, the compression eect to spinal cord or nerve roots, allowing the comparison of the cerebrospinal¯uid (CSF) and cyst contents.…”

Symptomatic Fourth Ventricle Arachnoid Cyst Extending to the Upper Border of the Dens of the Axis: A Case Report and Review of the Literature

“…There have been 12 cases reported by different authors including our presented case. The common point of these cases is that they did not need a ventriculoperitoneal shunt procedure except one case in which a cystoperitoneal shunt was performed [21][22][23][24][25][26][27]. Different surgical techniques such as a neuroendoscopic approach were used on these patients with an arachnoid cyst located in the fourth ventricle [28].…”
