Spinal extradural arachnoid cysts: clinical, radiological, and surgical features.

The radiological appearances of spinal extradural arachnoid cysts.

Solitary Symptomatic Spinal Extradural Arachnoid Cyst Needing Surgical Treatment: A Series of Three Cases

Extradural arachnoid cysts are rare lesions which may produce symptoms by compressing the spinal cord or nerve roots. Surgery is the treatment of choice in such lesions but asymptomatic patients can be managed conservatively. We present three cases of symptomatic extradural arachnoid cysts managed at our institute. Magnetic resonance imaging (MRI) done in all cases showed an extradural arachnoi...

Posterior spinal cord herniation into an extradural thoracic arachnoid cyst: surgical treatment. Case report and review of the literature.

The authors describe the case of a 2-year-old boy who experienced progressive spastic paraparesis for several months. Magnetic resonance imaging revealed an extensive extradural arachnoid cyst at the T3-L1 levels and posterior spinal cord herniation at T3-4. Surgical release of the neck of the hernia and total resection of the arachnoid cyst were performed. The patient had good clinical recover...

Non-communicating extradural arachnoid cyst of dorsal spine.

Extradural arachnoid cyst in the spine is an uncommon cause of spinal cord compression in the paediatric population. Most reported cysts have communication with the intrathecal subarachnoid space through a small defect in the dura. The reported child had spinal cord compression caused by a large spinal extradural arachnoid cyst in dorsal spine that did not communicate with the intradural subara...

Multiple extradural spinal arachnoid cysts: a case report and review of the literature

Extradural spinal arachnoid cysts are rare lesions, which may become symptomatic due to mass effect. Multiple cysts are even rarer of which few are reported to date. A 17-year-old male with acute onset urinary retention and progressive paraparesis is presented. Magnetic resonance imaging of spine revealed multiple spinal extradural arachnoid cysts located dorsal to the spinal cord, causing mass...
