摘　　要：目的 :分析总结脑内等密度占位性病变的CT征象及诊断途径 ,加强对此类疾病的认识 ,提高诊断准确率。方法 :回顾分析经病理或治疗随访证实的 1 1 6例脑内等密度占位性病变的CT征象特点 ,其中 1 0 9例行CT增强检查。结果 :1 1 6例中 ,确诊主要途径为 :仅通过CT平扫确诊 1 0例 ,结合CT平扫及增强确诊 5 9例 ,结合病史确诊 1 6例 ,结合临床查体确诊 9例 ,结合其他影像或实验室检查确诊 1 5例。脑瘤 87例 ,其中胶质瘤 34例、转移瘤 31例、脑膜瘤 1 0例、垂体瘤 5例、其他 7例 ,亚急性硬膜外或硬膜下血肿 1 5例 ,脑脓肿 7例 ,脑血管畸形 4例 ,脑囊虫病 3例。结论 :通过仔细分析CT平片和全面结合病史、临床查体、其他检查 ,提示脑内占位性病变 ,并尽可能做出神经功能定位 ,再辅以CT增强 ,必要时随访 ,对于正确诊断脑内等密度占位性病变 ,减少漏诊 ,避免误诊 ,非常重要。Objective:To analyse the CT features of intracerebral space occupy lesion with isodensity,and to improve the correct diagnostic rate.Methods:116 cases confirmed by pathology or clinical were analyzed retrospectively,of which 109 cases were performed contrast enhancement.Results:Of 116 cases,10 cases were diagnosed mainly by plain scan,59 cases by plain scan and contrast enhancement,16 cases by CT scan and medical records,9 cases by CT scan and medical examination,15 cases by CT scan and other examination.Of all the cases,there were intracerebral tumors in 87 cases,including glioma (n=34),metastatic tumor (n=31),meningioma (n=10),pituitary tumor (n=5),and others (n=7),epidural space or cavum subdural hematoma (n=15),brain abscess in 7 cases,cerebrovascular malformation in 4 cases,cysticercosis of brain (n=3).Conclusion:It is important for the CT diagnosis of intracerebral space occupy lesion with isodensity,analyzing carefully plain scan,overall combining medical records,physical and other examinations.Contrast enhancement and investigation at all times is important if necessary.
