title: Radiological diagnosis of spinal arachnoid cysts: A pictorial essay.
abstract: Spinal arachnoid cysts (AC) are intraspinal extramedullary loculated cerebral spinal fluid collections. They are relatively uncommon lesions. Spinal AC often cause symptoms such as pain, weakness and radiculopathy. In this pictorial essay we demonstrate the main radiological features of spinal AC, as well as symptoms and complications associated with them. We also describe the main differential diagnoses.
