Objective: Surgical management of symptomatic perineural cysts (Tarlov cysts) remains a matter of debate. Based on a pathomechanism which assumes a valve mechanism allowing CSF to enter the cyst through microcommunications at the distal dural sleeve of the nerve root, we propose a microsurgical approach[for full text, please go to the a.m. URL]
