A 19-year-old male was admitted to our hospital with a 5 year history of right low back pain. MR images showed an epidural mass which located on the posterolateral side at the T12-L1 level and extended through the right intervertebral foramen into the paraspinal muscles. Excision of the intramuscular and epidural lesions was performed and his symptom quickly improved. Histopathological examination of the mass revealed a cavernous hemangioma. It may affect any part of neuraxis, however cavernous hemangiomas located at the spinal epidural space are rare and particularly the lesions which grow continuously into the paravertebral muscles are very rare. Radiological presentation of this case was confusing in the preoperative diagnosis. It is important that we know the clinical, developmental and radiological characteristics of cavernous hemangiomas.
一名19岁男性因右下腹疼痛5年入住我院。磁共振成像显示硬膜外肿块位于T12-L1水平的后外侧，并通过右椎间孔延伸至椎旁肌。对肌肉内和硬膜外病变进行了切除，其症状迅速改善。肿块的组织病理学检查显示为海绵状血管瘤。它可能影响神经轴的任何部位，然而位于脊髓硬膜外间隙的海绵状血管瘤很少见，特别是那些持续生长到椎旁肌的病变非常罕见。该病例的放射学表现术前诊断存在混淆。了解海绵状血管瘤的临床、发育和放射学特征很重要。
