Arachnoiditis is inflammation of the arachnoid mater, most often spinal, caused by infection, subarachnoid hemorrhage, surgery, or contrast agents. Clinical: radicular pain, numbness, weakness, and sometimes sphincter disturbance. Imaging shows clumped nerve roots. Treatment: treat the underlying cause, pain management, physical therapy, and rehabilitation; prognosis varies, and chronic pain is common.
