目的:报道1例头颅MRI表现酷似颅内感染的多灶性脑梗死。方法:患者行头颅MRI检查,脑脊液等检测,脑标本行多部位病理检查。结果:MRI:两侧额叶及胼胝体膝部、体部多发片状异常信号,T1WI稍低信号,T2WI稍高信号,FLAIR高信号,DWI稍高信号,增强后病灶环形强化。病理诊断:脑动脉重度粥样硬化伴大脑顶叶、基底节、胼胝体及脑桥多发梗死伴出血灶形成。结论:多灶性脑梗死头颅MRI增强亦可出现酷似颅内感染的多灶性环型增强。
OBJECTIVE: To report a case of multifocal cerebral infarction with head MRI manifesting intracranial infection. Methods: Patients underwent cranial MRI examination, cerebrospinal fluid and other tests, brain specimens multi-site pathological examination. Results: MRI showed multiple anomalous flaps in the frontal lobe and corpus callosum on both sides of the body, with slightly lower T1WI signal, slightly higher T2WI signal, higher FLAIR signal and slightly higher DWI signal. Pathological diagnosis: Cerebral arterial atherosclerosis with parietal lobe, basal ganglia, corpus callosum and pontine multiple infarction with hemorrhage formation. CONCLUSIONS: Multifocal enhancement of MRI in patients with multifocal cerebral infarction may also appear multifocal ring resection that resembles intracranial infection.
