Abstract
- About 25% of intrasacral perineural cyst cause sciatica resembling lumbar disc herniation or lumbar stenosis. We report a case of sacral perineural cyst in a 38-year-old female who complained of sciatica and neurogenic intermittent claudication. Delayed X-ray after 3 hours from initial myelogram revealed round cyst at the sacral canal. CT and MRI revealed a cystic mass which has cerebrospinal fluid(CSF) signal intensity. The patient underwent surgery via sacral laminotomy and ligation of cyst including S2 nerve root. The patient returned to work with complete relief of symptoms.
