“…Magnetic resonance imaging is valuable in diagnosing a cyst, whereas CT myelography is useful in detecting the communication of the cyst with the subarachnoid space. 8,12,15 Longstanding hydrostatic pressure within the cyst can cause osseous changes in the spine, such as widening of the interpedicular distance, erosion of the pedicle and posterior elements, scalloping of the posterior aspects of the vertebral bodies, and kyphoscoliosis. 8,10 Surgical Treatment For asymptomatic patients, conservative treatment with observation is recommended.…”

✓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 ligation of the communicating pedicle and closure of the dural defect. In the present paper the authors review the literature and discuss the clinical and pathological features, mechanisms of pathogenesis, neuroimaging characteristics, and surgical management of spinal extradural arachnoid cysts. The surgical technique for removal of these lesions is illustrated in a patient with a large thoracolumbar spinal extradural arachnoid cyst causing neurogenic claudication.

“…In our case, the only arachnoid membrane lined OMC, seemed to be protruding into orbital apex while the dural cuff was terminated at intracranium proximal to orbital apex. It is also observed in type II extradural meningeal cyst with neural tissue at spine (10). To the best of our knowledge, there were no reports about arachnoid cyst of oculomotor cistern at orbital apex.…”

Arachnoid Cyst in Oculomotor Cistern

Oculomotor cistern is normal anatomic structure that is like an arachnoid-lined cerebrospinal fluid-filled sleeve, containing oculomotor nerve. We report a case of arachnoid cyst in oculomotor cistern, manifesting as oculomotor nerve palsy. The oblique sagittal MRI, parallel to the oculomotor nerve, showed well-defined and enlarged subarachnoid spaces along the course of oculomotor nerve. Simple fenestration was done with immediate regression of symptom. When a disease develops in oculomotor cistern, precise evaluation with proper MRI sequence should be performed to rule out tumorous condition and prevent injury of the oculomotor nerve.

“…The predilection of a neurenteric cyst to be located at the anterior part of the spinal canal or the presence of septae, which are uncommon in arachnoid cysts, may aid in the diagnosis of this type of cyst. 2 Regardless, the diagnosis of a neurenteric cyst can only be confirmed after histopathological examination.…”
