Abstract
Arachnoid cysts are formations, which contain liquid, located between arachnoid and pia mater, or formed by the duplication of arachnoid membrane. Intracranial arachnoid cysts are frequently seen; however, spinal arachnoid cysts are rare. Twelve-years-old female patient was admitted to our hospital with the complaints of back pain, tingling and pain in lower extremities, and inability to walk preceeded by falling onto ground. Neurologic examination revealed spastic paraparesis. Thoracal MRI study showed intramedullar arachnoid cyst located at T2-T4 levels. The patient went through surgical resection and her findings disappeared on 25th day of admission. Complete recovery was observed at 3rd month after the surgery. In post-traumatic arachnoid cysts, early diagnosis and appropriate surgical intervention may result in recovery of neurological findings as in our case.
