Spinal Expanding Lesions Extradural Spinal Arachnoid Cysts

The clinical features of benign convulsions with mild gastroenteritis (CwG) were studied retrospectively in 62 patients hospitalized (Jan 2000-March 2006) at St Mary's Hospital, Kurume City, Japan. Viral infections confirmed in 71% of fecal specimens were rotavirus in 30 patients, norovirus in 9, sapovirus in 2, adenovirus in 2, and coxsackievirus A4 in 1. Age of patients with norovirus (16.7 +...

Spinal 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...

Spinal Extradural Arachnoid Cyst

A 48-year-old male presented with progressive leg weakness. Magnetic resonance imaging and computed tomography myelography showed an extradural arachnoid cyst extending from the T-12 to L-2 levels in the thoracolumbar region. The cyst was confirmed at surgery and completely removed. This surgical intervention achieved improvement in the neurological symptoms.

Spinal Extradural Arachnoid Cyst

A spinal extradural arachnoid cyst (SEAC), which is mostly found at the thoracic spine, is a rare disease, accounting for approximately 1% to 3% of spinal tumors. SEAC patients are generally men in their 20’s, 30’s, or 50’s. SEACs are most commonly found in the middle or lower thoracic spine, and less frequently found in the lumbar region, although they can be detected at any lesion of the spin...
