Abstract
BACKGROUND: Lumbar intraspinal ganglion cysts are a rare cause of lumbar radiculopathy. Often these cysts are extradural and next to facet joints. Sometimes they are related to ligamentum flavum or posterior longitudinal ligament. Lumbar intradural ganglion cyst has never been reported to date.
CASE DESCRIPTION: Herein, the authors report on a fifth lumbar intradural ganglion cyst in an elderly patient presenting with insidious onset of left-sided lower limb pain. A lumbar spine magnetic resonance imaging (MRI) revealed a left-sided ventrolateral intraspinal cystic lesion abutting on the fifth lumbar vertebral body with ring enhancement of the cyst wall. At operation, no lesion was found related to the facet joint or in the epidural space. Instead, a dura-based septated ganglion cyst was noted intradurally. The patient's discomfort was completely relieved postoperatively. A follow-up MRI showed complete removal of the cyst.
CONCLUSIONS: The authors showed the first case report on a lumbar intradural dura-based ganglion cyst in an elderly patient, leading to compressive radiculopathy. After surgery, total removal of the cyst was achieved and the patient's discomfort was completely relieved. The origin and pathogenesis of the lumbar intradural ganglion cyst are still unknown. Surgical extirpation is regarded as the treatment of choice.
