Lumbar Discal Cyst as a Rare Cause of Low Back Pain and Radiculopathy

초록

Discal cysts that lead to low back pain and radiculopathy are uncommon. To date, only a few cases have been reported in the literature. Herein, we report the case of a 30-year-old man who experienced low back pain and radiculopathy due to a lumbar discal cyst. On magnetic resonance images, an extradural cystic mass was seen as a low signal intensity on T1-weighted images and a high signal intensity on T2-weighted images, respectively. The cyst was a grossly oval-shaped mass with hematoma connected to the adjacent intervertebral disc. Radiculopathy and low back pain were dramatically relieved after surgical removal. As in our experience and other case reports, surgical resection can be considered as the first treatment option in patients with symptomatic discal cysts.
