Abstract

Japanese encephalitis (JE) is a common infection caused by the Japanese encephalitis virus in Southeast Asia, which is transmitted to humans through Culex mosquitoes. Magnetic resonance imaging (MRI) is used to diagnose JE, which is often characterized by the presence of bilateral symmetric thalamic involvement. Here, we report a rare case of JE characterized by leptomeningeal enhancement without thalamic involvement. This leptomeningeal enhancement disappeared with the treatment; however, new non-specific multifocal and bilateral high signal intensities in the cerebral white matter were found on follow-up MRI.

일본뇌염은 동남아시아에서 일본뇌염 바이러스에 의해 발생하는 흔한 감염이며, Culex 모기에 의해 인간으로 전파된다. 일본뇌염에서의 자기공명영상은 양측의 시상 침범이 있는 것이 흔한 소견이다. 저자들은 시상 침범 없이 연수막 조영증강의 형태로 나타난 일본뇌염의 드문 증례에 대해 보고하고자 한다. 치료 후, 연수막 조영증강은 사라졌으며, 비특이적인 다발성 및 양측의 고신호강도가 추적 MRI 영상에서 새롭게 나타났다.
