Baastrup's Disease as a Rare Cause of Cauda Equina Syndrome: A Case Report

"Baastrup's disease" is a relatively common anatomical condition, controversially recognized as a possible cause of back pain but frequently missed by clinicians of different specialties. We present a rare case of Baastrup's disease causing compression to the cauda equina nerves due to the formation of a large pseudotumoral epidural mass. The patient underwent a successful surgical decompression with remarkable improvement in her neurological presentation. The histopathological findings consisted of increased collagen deposition and chondroid metaplasia.

Clinicians should be aware of possible cauda equina syndrome in rare cases of Baastrup's disease due to pseudotumoral mass compression in the lumbar spine.
