Synovial cysts are rarely observed in cases with epidural compressive syndromes. They are intraspinal lesions that may mimic disc hernias by causing radicular symptoms. A 28-year-old female patient presented with radicular complaints such as back pain for 6 months, urinary incontinence for 1 month, and progressive right leg pain and numbness for the last 2 weeks. Physical examination revealed weakness (4/5) in gastrocnemius muscle, right L5-S1 hypoesthesia, and urinary incontinence. On magnetic resonance imaging, an intraspinal cyst was seen at the level of L5-S1. The patient was operated with bilateral L5 hemipartial laminectomy, foraminotomy, and cyst excision. Her symptoms, especially urinary incontinence, regressed at the early postoperative period and completely disappeared together with normal motor and sensory examination findings at the control visit at 1 year.
