Abstract

Cerebral malaria is associated with high mortality and morbidity in patients infected with Plasmodium Falciparum. The mechanisms of cerebral malaria include sequestration of parasitized red blood cells in brain capillaries, production of cytokines, immune cell/platelet accumulation, and release of microparticles, resulting in disruption of the blood-brain barrier, which caused brain injuries. The severity of this reflects on neurological findings ranging from simple delirium to profound coma. We herein present unique magnetic resonance imaging findings of a case of fulminant cerebral malaria as computed tomography studies usually underestimate the extent of cerebral involvement in malaria.

摘要

脑型疟疾与感染恶性疟原虫的患者的高死亡率和高发病率相关。脑型疟疾的发病机制包括寄生的红细胞在脑毛细血管中滞留、细胞因子的产生、免疫细胞/血小板的积聚以及微粒的释放,从而导致血脑屏障破坏,进而引起脑损伤。其严重程度反映在从单纯谵妄到深度昏迷的神经学表现上。我们在此呈现了一例暴发性脑型疟疾独特的磁共振成像结果,因为计算机断层扫描研究通常会低估疟疾时脑受累的程度。
