目的提高对脑血管畸形合并慢性扩张性脑内血肿这一临床上少见疾病的认识。方法回顾分析１０例脑血管畸形合并慢性扩张性脑内血肿的临床表现及ＣＴ扫描。结果病灶表现为慢性颅内占位性病变，ＣＴ扫描呈现高、低混杂密度及明显的占位效应，同时伴有环形、不规则或结节状强化。结论脑血管畸形合并慢性扩张性脑内血肿易误诊为脑瘤或脑脓肿，应开颅手术，清除血肿切除病灶，并送病理检查以明确诊断。
Objective To improve the understanding of cerebrovascular malformation associated with chronic dilated intracerebral hemorrhage, a clinically rare disease. Methods The clinical manifestations and CT scans of 10 cases of cerebrovascular malformation combined with chronic dilated intracerebral hemorrhage were retrospectively analyzed. Results The lesions showed chronic intracranial space-occupying lesions. CT scan showed high and low miscellaneous density and significant mass-bearing effect, accompanied by annular, irregular or nodular enhancement. Conclusions Cerebrovascular malformations combined with chronic dilated intracerebral hematoma are often misdiagnosed as brain tumors or brain abscess. The craniotomy should be performed to remove the hematoma and remove the pathological examination to confirm the diagnosis.
