Abstract:
Intradural disc herniation is a very rare condition, and multiple intradural disc herniations have not been reported to date. The latter may be confused with intradural extramedullary (IDEM) spinal tumors. Here, we report a case of multiple intradural disc herniations masquerading as multiple IDEM tumors and review the relevant literature. We retrospectively reviewed the patient's medical chart, reviewed the intraoperative microscopic findings, and reviewed of PubMed articles on intradural disc herniation. The masses considered to be IDEM tumors were confirmed to be multiple intradural disc herniations. A nonenhancing mass was found to have migrated along the intra-arachnoid space. Two enhancing masses could not migrate because of adhesion and showed peripheral neovascularization. We report an extremely rare case of multiple intradural lumbar disc herniations showing diverse enhancing patterns and masquerading as multiple IDEM tumors. In case of multiple enhancing IDEM masses suspected preoperatively, surgeons should consider the possibility of intradural disc herniation.
