Pure Extradural Cavernous Hemangioma Presenting as a Lumbar Radiculopathy

Pure epidural cavernous hemangiomasof the spinal canalare extremely rare. We describe a case of lumbar epidural hemangiomasuspected as a lumbar radiculopathyin a 78-year-old man who presented with a 1-month history of the low back pain and right lower extremity pain. An electrodiagnostic study demonstrated right L4 radiculopathy. Noncontrast magnetic resonance image (MRI) showed a nodular lesion suggestive of a sequestered disc with compression of right L4 root, most likely. Contrast MRI revealed an oval enhancing nodular lesion, 1.40.5 cm in size, indicative of a hemangiomain right anterior epidural spaceat L4 level. He underwent an excisional biopsy. The pathological diagnosis was cavernous hemangioma. His symptoms resolved after the operation. Spinal epidural cavernous hemangiomashould be considered as a cause of a lumbar radiculopathy.
