  • Title: Lumbar vertebral hemangioma with extradural extension, causing neurogenic claudication: a case report.
    Author: Jouibari MF, Khoshnevisan A, Ghodsi SM, Nejat F, Naderi S, Abdollahzadeh S.
    Journal: Acta Med Iran; 2011; 49(10):697-700. PubMed ID: 22071649.
    Abstract:
    The authors present a rare case of lumbar vertebral hemangioma extending to the epidural space with a bisected appearance and impinging on thecal sac. This 52-year-old lady presented with one year history of low back pain and bilateral leg radiation. Plain radiography showed vertical linear streaks at L2 vertebral body and axial computed tomography (CT) scan revealed small "polka dot" appearance within the vertebral body. Magnetic resonance imaging (MRI) showed low signal intensity on T1-weighted images in L2 vertebral body which was not characteristic for hemangioma. The patient underwent an L2 laminectomy, spinal canal decompression and posterior spinal instrumentation. This study indicates that lumbar vertebral hemangioma can extend to the epidural space and cause neurologic symptoms. Magnetic resonance imaging may not show diagnostic features, especially in active lesions and plain radiography and CT scan may be helpful.
