1 CLINICAL HISTORY

A previously healthy 7-year-old boy presented with generalized tonic-clonic seizures for approximately 1 month. He was the first child of unrelated, healthy parents and had exhibited normal development. MR imaging demonstrated a large, right-sided temporal lobe mass-like lesion measuring 44 × 25 × 24 mm. The lesion exhibited hypointense on T1-weighted images and a distinct heterogenous high signal intensity on T2/FLAIR images with nodular contrast enhancement (Figure 1). He underwent surgical gross total resection of the tumor and postoperatively he was free of symptoms. Eight months post-surgery, neuroimaging gave no indication of tumor recurrence.

1 临床病史

一名先前健康的 7 岁男孩出现全身强直阵挛性癫痫发作约 1 个月。他是无血缘关系的健康父母的第一个孩子，并且发育正常。磁共振成像显示右侧颞叶有一个巨大的肿块样病变，尺寸为 44 × 25 × 24 毫米。病变在 T1 加权图像上表现出低信号，在具有结节对比度增强的 T2/FLAIR 图像上表现出明显的异质高信号强度（图 1）。他接受了肿瘤全切除手术，术后没有出现任何症状。手术后八个月，神经影像学检查没有显示肿瘤复发的迹象。
