An Intradiscal gas collection, referred to as the vacuum disc phenomenon (VDP) is a relatively common finding on radiographic studies of the lumbar spine, whereas gas-containing lumbar disc hernia is rarely observed. We report a case of a patient with left leg pain, provoked by a radiographically and surgically documented L4-5 gas containing disc hernia.
