Abstract
CT and MR imaging studies were performed in a 3-year-old boy with infantile fibromatosis arising from the infratemporal fossa and extending into the middle cranial fossa. On CT scans, the lesion was hyperattenuating (44-49 Hounsfield units [HU]), enhancing significantly after application of contrast material (63-66 HU). The MR images showed a multilobulated lesion of heterogeneous signal intensity. The tumor was markedly hypointense on T2-weighted images and slightly hypointense on T1-weighted images relative to brain tissue, iso- or slightly hyperintense relative to tongue muscle on both T2- and T1-weighted images, and enhanced strongly after administration of gadopentetate dimeglumine.
摘要
对一名3岁患有起源于颞下窝并延伸至中颅窝的婴儿纤维瘤病的男孩进行了CT和MR成像研究。在CT扫描中，病变呈高密度（44 - 49亨氏单位[HU]），注射造影剂后显著强化（63 - 66 HU）。MR图像显示一个信号强度不均匀的多叶状病变。相对于脑组织，该肿瘤在T2加权图像上呈明显低信号，在T1加权图像上呈轻度低信号，在T2和T1加权图像上相对于舌肌呈等信号或轻度高信号，注射钆喷酸葡胺后强化明显。
