| 摘 要： | 目的 探讨CT和MRI对室管膜下巨细胞型星形细胞瘤(subependymal giant-cell astrocytoma, SEGA)的诊断价值.方法 回顾性分析5例经临床病理证实为SEGA的CT和MR3表现及临床资料.结果 本组全部5例SEGA均伴发结节性硬化,CT表现为室间孔或侧脑室前角类圆形略高密度结节(边界清楚,多呈明显均匀强化),室管膜下结节状钙化,脑实质错构瘤.MRI表现为室间孔或侧脑室前角类圆形结节(T1WI呈等低信号,T2WI呈稍高信号),室管膜下、皮质和皮质下多发稍长T1稍长T2病灶.结论 CT和MRl相结合是SEGA的最佳影像检查方法,结合患者特征性临床表现,可作出较明确诊断.

| Abstract: | Objective To evaluate the diagnostic value of CT and MRI on subependymal giant-cell astrocytoma (SEGA). Methods Appearances of CT, MRI and clinical data in 5 cases with SEGA pathologically proved were analyzed retrospectively. Results All 5 cases in this group were accompanied with tuberous sclerosis. Based on CT findings, round-like nodules with slightly high density were appeared in the inter-ventricular foramen or frontal horn of lateral ventricle with clear border and uniform enhancement. The sub-ependy... |
