ABSTRACT
Arachnoid cysts are fluid-filled sacs of the arachnoid layer which are composed of substances similar to but not equal to the cerebrospinal fluid (CSF).[1] Spinal arachnoid cysts are one group of rare spinal expansions that have both baffled and intrigued the curiosity of neurologists and neurosurgeons for years.[2] They are considered as rare causes of spinal cord compression.[3] The exact causes of these cysts still remains unclear, but the most accepted explanation is the existence of certain areas of weakness in the spinal dura. The symptoms depend on the location of these cysts. Magnetic resonance imaging (MRI) is mainly used for its diagnosis. Therapeutic management of these cysts depends on the clinical presentation. Surgical removal is usually indicated for patients who are having neurological impairment.[4]
