Discal cyst is an intraspinal cyst with a distinct communication with the corresponding intervertebral disc. It is a rare condition and could present with radiculopathy similar to that caused by lumbar disc herniation. We present a patient with a large discal cyst in the ventrolateral epidural space of the $5^{th}$ lumbar vertebral (L5) level that communicated with the adjacent $4^{th}$ lumbar and $5^{th}$ lumbar intervertebral disc, causing L5 radiculopathy. We alleviated the radiating pain with selective transforaminal epidural blocks.
