This report is presented to demonstrate the image findings of a patient with a recent onset of progressive spinal cord compression caused by a giant arachnoid cyst of the thoracolumbar spine. The patient presented with gradual onset paraparesis and the diagnosis of arachnoid cyst was made on MRI. Surgery was successful with respect to in-toto removal of the cyst, following which there was rever...

Occasionally, a posterior fossa arachnoid cyst can induce compression of the spinal cord and cause syringomyelia. Here, we report the case of a 29-year-old man with both progressive shoulder pain and gait disturbance, who was found to have a huge retrocerebellar arachnoid cyst associated with syringomyelia. Accordingly, posterior fossa decompression and arachnoid cyst excision were performed. P...

Spinal arachnoid cysts are uncommon benign lesions that occur in the spinal axis, and can cause spinal cord or nerve roots compression and may become clinically relevant. The authors report a 49-year-old woman who presented progressive onset of cervical pain with distal paraesthesia of the upper limbs associated to an intramedullary arachnoid cyst in the mid-cervical spine diagnosed by MRI. Fro...

Spinal arachnoid cyst is a rare cause of myelopathy secondary to spinal cord compression. We report a case presenting extradural arachnoid cyst of probable traumatic origin leading to irreversible neurological deficits including paraparesis and neurogenic bladder. The patient presented progressive paraparesis and voiding difficulty. Magnetic resonance imaging (MRI) of the spine revealed long se...

BACKGROUND A rare cause of spinal cord compression is spinal arachnoid cysts. Symptoms are caused by spinal cord compression, however, asymptomatic patients have been also reported. Treatment options depend upon symptom severity and clinical course. CASE DESCRIPTION We report the case of a 47-year-old patient who developed an intramedullary arachnoid cyst after removal of an intradural extram...

Spinal arachnoiditis (SA) is a rare and delayed complication of aneurysmal subarachnoid hemorrhage (aSAH). We present a case of delayed SA associated with thoracic and lumbar arachnoid cysts in a patient with aSAH secondary to a ruptured vertebral artery aneurysm. The patient underwent a thoracic laminectomy for decompression of the spinal cord, lysis of arachnoid adhesions, and fenestration of...

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 of the cyst is unique and the presenting complaint rare.

Arachnoid web is a rare disease entity that can cause progressive myelopathy and most often develops at the upper thoracic level. Its pathophysiology unclear, but may be associated with degeneration of septum posticum in dorsal subarachnoid space, which alters flow cerebrospinal fluid (CSF) subsequently leads to cord compression syringomyelia. It presents pain, paresthesia, extremity weakness. ...
