目的 探讨隐匿性脑血管畸形合并慢性扩张性脑内血肿 (CEIH)的 CT及临床表现。方法 回顾性分析临床误诊 ,后经手术、病理诊断的脑血管畸形合并 CEIH 10例患者的头颅 CT及临床资料。结果 10例临床表现及 CT所见均显示一般占位性病变的征像 ,CT平扫见脑皮质下区髓质内的高、次高、低等混杂密度块影 ,三面水肿较重而一面较轻 ;增强扫描见环状、结节状或不规则强化 ,有较完整包膜 ,其占位效应较一般单纯出血略显著者其临床病程较长 ,有反复发作及进行性加重的特点。结论 本病根据临床和 CT诊断较难 ,有上述 CT及临床特点者应考虑脑血管畸形合并 CEIH的可能 ,但最后须病理检查确诊。
Objective To investigate the CT and clinical manifestations of occult cerebrovascular malformations combined with chronic dilated intracerebral hematoma (CEIH). Methods The head CT and clinical data of 10 patients with cerebrovascular malformations who were misdiagnosed, surgically and pathologically diagnosed by CEIH were retrospectively analyzed. Results The clinical manifestations of 10 cases and CT findings showed signs of general space-occupying lesions. CT scan revealed high, sub-high and low-density mixed mass patches in the medulla of the subcortical region. Lighter; enhanced scan see ring, nodular or irregular enhancement, a more complete capsule, the placeholder effect is slightly more than the general simple bleeding of its longer clinical course, with recurrent and progressive increase in the characteristics. Conclusion The diagnosis of this disease based on clinical and CT more difficult, with the above CT and clinical features should consider the possibility of cerebrovascular malformations combined with CEIH, but the final pathological examination confirmed.
