Abstract

A case of acute thalamic hematoma not detected by computed tomography (CT) but unequivocally diagnosed by magnetic resonance imaging (MRI) is presented. A 79-year-old woman presented with acute left hemiparesis. The results of CT obtained on admission as well as on the seventh hospital day were negative for a hematoma. By contrast, serial MRIs exhibited chronological changes in the relaxation properties characteristics of acute hematoma in the thalamus. The case illustrates that contrary to widespread practice, CT cannot absolutely be relied on for the detection of acute intracerebral hematoma.

摘要

本文报道了一例急性丘脑血肿病例，该病例在计算机断层扫描（CT）上未被检测到，但通过磁共振成像（MRI）明确诊断。一名79岁女性出现急性左侧偏瘫。入院时及住院第七天的CT检查结果均显示血肿为阴性。相比之下，系列MRI显示丘脑急性血肿的弛豫特性随时间发生变化。该病例表明，与普遍做法相反，CT不能绝对依赖于检测急性脑内血肿。
