摘要

颅内出血在磁共振成像(MRI)上的表现是复杂的,取决于其随时间的演变。MRI检测超急性出血的能力一直存在争议,因为它似乎取决于几个因素(即成像延迟,MRI场强,成像技术)。我们提出的第一例颅内出血发生在MRI采集期间,在一个61岁的女性患有严重缺氧缺血性脑病从自杀企图上吊。血肿的影像学特征不同于以往的描述,因为它缺乏典型的周围T2和T2*低密度,通常见于超急性血肿。我们讨论以前的文献,以解释这些特殊的成像特征。

Spot the new lesion: a case report of intra-MRI cerebral haemorrhage with discussion of previous literature.

The appearance of intracranial haemorrhage on magnetic resonance imaging (MRI) is complex and depends on its evolution over time. The ability of the MRI to detect hyperacute haemorrhage has been debated as it seems to depend on several factors (ie, delay of imaging, MRI field strength, imaging technique). We present the first case of intracranial haemorrhage occurring during MRI acquisition in a 61-year-old female suffering a severe hypoxic-ischaemic encephalopathy from a suicide attempt by hanging. The imaging characteristics of the haematoma differ from what has been described in the past, as it lacks the typical peripheral T2 and T2* hypointensity usually seen in hyperacute haematomas. We discuss previous literature in order to explain these peculiar imaging features.
