脑脓肿的CT表现及临床66例分析

The Computed Tomographic Manifestations of Brain Abscess (An Analysis of 66 Cases)

收集CT扫描和病理证实的66例脑脓肿进行了分析,发现CT定位诊断率为100％,定性诊断率92.4％。3例误诊患者中,2例为脑胶质瘤,1例为转移癌囊性变。脑肿瘤CT扫描特点:圆形或卵圆形厚度一致环影,内外壁光滑平整,环内为均匀一致的低密度充盈于环腔,均值为18.51Hu。占位效应明显。并对不同病理阶段的CT表现进行了讨论。

Sixty six cases with brain abocess confirmed by computed tomography and pathology have been collected and analysed. It was found that the rate of niveau duagnosis by CT was 100% and that of qualitative diagnosis was 92.4%. Of the three misdiagnoses, 2 were cerebral astrocytoma and 1 was cystic degeneration of metastatic carcinoma. The characteristics of brain tumor in computed tomogra- phy revealed: round or oval circular image of equal thickness, with smooth and regular surface both in- ternally and externally,Even material of low density filled the circular cavity,with average CT value of 18.51 Hu. The space occupying effect was distinct. The CT manifestations of different pathological stages have been discussed.
