脊椎血管瘤的影像学表现及其诊断(附14例分析)

目的　分析脊椎血管瘤的X线、CT和MRI表现 ,评价其诊断价值。方法　经临床及手术病理证实的脊椎血管瘤共 14例 ,均行X线平片检查 ,其中 9例行CT扫描 ,6例作MR检查 ,CT和MR同时检查者 2例。结果　胸椎 10例 ,腰椎 3例 ,颈椎 1例。单个椎体受累者 11例 ,多个椎体受累者 3例 ;8例表现为典型的“栅栏状”或“蜂窝状” ,5例为椎体不规则破坏 ,其中 3例伴有椎体压缩 ;肿瘤突入椎管者 1例 ;X线和CT误诊者 2例 ,6例经MR检查确诊。结论　X线平片检查对典型的较大的脊椎血管瘤具有诊断意义 ,而CT和MR对不典型血管瘤的定位定性诊断具有十分重要的价值。

Imaging Features and Diagnosis of Vertebral Hemangioma

Objective To analyse the features of vertebral hemangioma and inaging diagnostic value of vertebral hemangioma.Methods There were 14 cases with hemangioma proved by clinic and pathology.X-ray plain was performed in all cases,of which 9 cases were performed by CT scan and,only 6 cases were taken MR,and 2 cases had both CT and MR scan.Results The tumors were located in thoracic spine in 10 cases,in lumbar spine in 3 cases and in cervical spine in 1 case.8 cases showed typically fence-like or nest-like;the verterea were irregularly destroyed in 5 cases,of which 2 cases were associated with vertebrea collapsing.According to the features in plain film and CT scan,there were 2 cases misdiagnosed,but 6 cases were all made a correct diagnosis on the base of MR before surgry.Conclusion Typical vertebral hemangima can be diagnosed correctely according to plain film or CT while MR plays an important role in atypical cases.
