Abstract

A 16-year-old girl had an ependymoma at the L2 and L3 level that bled into the dural sac, presenting clinically as intracranial subarachnoid hemorrhage. MR depicted the tumor and hemorrhage on both T1- and T2*-weighted images. The blood in the dural sac appeared hyperintense on the T1-weighted images.

摘要

一名16岁女孩在L2和L3水平患有室管膜瘤，肿瘤出血进入硬脊膜囊，临床上表现为颅内蛛网膜下腔出血。磁共振成像（MR）在T1加权像和T2*加权像上均显示出肿瘤和出血情况。硬脊膜囊内的血液在T1加权像上呈高信号。
