Vertebral hemangiomas are common lesions and usually considered benign. A rare subset of them, however, are characterized by extra-osseous extension, bone expansion, disturbance of blood flow, and occasionally compression fractures and thereby referred to as aggressive hemangiomas. We present a case of a 67-year-old woman with progressive paraplegia and an infiltrative mass of T4 vertebra causing mass effect on the spinal cord. Multiple conventional imaging modalities were utilized to suggest the diagnosis of aggressive hemangioma. Final pathologic diagnosis after decompressive surgery confirmed the diagnosis of an osseous hemangioma.
椎体血管瘤是常见病变，通常被认为是良性的。然而，其中一小部分罕见类型的特征是骨外扩展、骨质膨胀、血流紊乱，偶尔还会发生压缩性骨折，因此被称为侵袭性血管瘤。我们报告一例67岁女性，患有进行性截瘫，T4椎体有浸润性肿块，对脊髓产生占位效应。采用多种传统成像方式提示侵袭性血管瘤的诊断。减压手术后的最终病理诊断证实为骨血管瘤。
