结节性硬化的CT征象分析

Analysis on CT signs of tuberous sclerosis

目的分析结节性硬化的CT征象以提高对本病的认识。方法14例临床证实的结节性硬化患者均经脑部与腹部CT平扫,其中,6例患者又经对比增强CT扫描。对所有患者的CT表现与临床资料进行了回顾性分析。结果在14例结节性硬化患者中,室管膜下结节见于14例,室管膜下巨细胞星形细胞瘤4例,皮质和皮质下结节6例,脑白质病变2例,肾脏血管平滑肌脂肪瘤4例,肝脏肿块1例。结论脑部与肾脏结节性硬化具有利于确诊本病的特征性CT征象。

Objective To analyze the CT signs of tuberous sclerosis and to elevate the cognition for this disease. Methods Fourteen patients with clinically proved tuberous sclerosis underwent conventional plain CT scans of the brain and abdomen, of whom, 6 patients underwent additional contrast-enhanced CT scans. The CT findings and clinical data in all patients were analyzed retrospectively. Results Among 14 patients with tuberous sclerosis, subependymal tubers were found in 14, subependymal giant cell astrocytomas in 4, cortical and subcortical tubers in 6, cerebral white matter lesions in 2, renal angiomyolipomas in 4, and hepatic mass in 1. Conclusion The lesions of tuberous sclerosis occurring in brain and kidney have characteristic CT signs which may definitely diagnose this disease.
