    Abstract:
    OBJECTIVE: To evaluate whether treatment of spinal meningeal cysts that compress sacral spinal nerve roots is associated with relief of persistent genital arousal disorder. METHODS: In this case series we encountered a group of patients with persistent genital arousal disorder among a larger cohort undergoing a prospective outcomes study on the surgical treatment of symptomatic spinal meningeal cysts. Epidemiologic data were collected and the type, number, and location of the meningeal cysts in each patient were determined on magnetic resonance imaging. Postoperatively patients were asked to self-report whether their persistent genital arousal disorder was eliminated, significantly better, the same, or worse. RESULTS: In a cohort of 1,045 patients with symptomatic spinal meningeal cysts, we identified 11 with persistent genital arousal disorder; all were female and all had meningeal cysts in the sacral spinal canal causing sacral nerve root compression. In addition to persistent genital arousal disorder, all patients had other symptoms typical of sacral nerve root compression such as perineal, bladder, and bowel symptoms. Although multiple types of meningeal cysts were encountered, Tarlov cysts were the most common (8/11). Postoperatively, seven (64%) patients reported elimination of their persistent genital arousal disorder, three (27%) noted significant improvement, one (9%) said they were unchanged, and none experienced worsening with an average follow-up of 23 months ranging from 2 months to 6 years. Although Tarlov cysts were more numerous, the presence of persistent genital arousal disorder and the surgical outcomes appeared unrelated to the type of spinal meningeal cyst treated. CONCLUSION: Our case series suggests that sacral nerve root compression caused by spinal meningeal cysts can cause persistent genital arousal disorder. The presence of nerve root compression appears to be more important than the particular type of meningeal cyst involved. Microsurgical cyst treatment cured or significantly reduced persistent genital arousal disorder symptoms in 91% of the patients. LEVEL OF EVIDENCE: III.
