Spinal arachnoid cysts generaiiy communicate with the subarachnoid space. Theyare considered as benign entities and are rarely seen in neurosurgical practice (2, 9-11). Presentation with cornpressian of the spinal cord andi or roots may sametimes occur and this may be symptomatic, as myelopathy andi or radiculopathy (1-12). In this paper a case of intradural arachnoid cyst in the midthoracic re...

We describe a rare case of intradural-extramedullary primary spinal cysticercosis. A 42-year-old man visited our institute for lower back pain. He denied having consumed raw meet. Magnetic resonance (MR) images revealed an intradural pure cystic mass at the L3-L4 level. A radiologic diagnosis of spinal arachnoid cyst was established. Three years later, he complained of aggravated back pain, and...

Traumatic extradural arachnoid cyst is a rare entity. However, late appearance of paraparesis due to formation of an extradural arachnoid cyst as a sequel of brachial plexus injury is extremely rare and the literature regarding this issue is scarce revealing only 11 cases. Herein, we report a patient with delayed progressive spastic paraparesis appearing after a multilevel brachial plexus root ...

BACKGROUND Spinal cysts are rare findings in veterinary medicine, but they are increasingly recognized due to the availability of advanced imaging techniques. Extradural meningeal cysts in French Bulldogs have not been reported previously and arachnoid cysts (diverticula) have not been reported at the caudal lumbar (L6-L7) region in dogs. CASE PRESENTATION Two French Bulldogs, aged 5 and 8 ye...

Background: Spinal extradural arachnoid cyst is extremely rare. The longest SEACs that have been reported in previous studies involved no more than 5 spinal segments. This study presents a case of SEAC diagnosed from T9 to L4 and excised through a novel laminectomy/laminoplasty. Case presentation: A 22-year-old female presented with a 5-year history of progressive paraparesis and numbness in bo...

Intradural arachnoid cysts are a rare cause of spinal cord compression. In symptomatic cases neuropathic pain, gait disturbance, and paraparesis or quadriparesis are often present. Postoperative arachnoid cysts have rarely been reported. We describe a 56-year-old male who developed progressively enlarging arachnoid cysts with cauda equina syndrome and vertebral body erosion after lumbar surgery...

UNLABELLED Intradural arachnoid cysts are rare lesions that frequently arise posterior to the spinal cord in the thoracic spine region. Those located at the cervical spine level, anterior to the spinal cord are even rarer. The usual treatment of symptomatic intradural spinal cysts involves surgical removal through a posterior approach using a laminectomy or laminotomy. However, ventrally locate...
