초록

Human immunodeficiency virus (이하 HIV) 뇌염의 영상 소견은 양측성, 대칭성으로, 미만성 혹은 반점상으로 양쪽 기저핵, 소뇌, 뇌간, 난형 중심에 T2 신호 강도가 증가된다. 특히 가장 흔하게 난형 중심을 침범한다. 대부분의 HIV 뇌염 증례들은 뇌의 위축을 동반한다. HIV encephalitis 환자에서 뇌 위축 없이, 양측성으로 난형 중심에 신호 강도가 증가된 확산강조영상은 보고된 바가 없다. 따라서 우리는 이 증례를 보고하며 또한 HIV 감염에 대한 임상 정보와 함께 확산강조영상에서 양측성으로 난형 중심에 신호 강도가 증가한다면 영상의학과 의사는 급성 HIV 뇌염의 가능성을 고려할 것을 제안한다.

Imaging finding of human immunodeficiency virus (HIV) encephalitis contain bilateral, symmetric, patchy, or diffuse increased T2WI signal intensities in the basal ganglia, cerebellum, brainstem, and centrum semiovale. In particular, the centrum semiovale is most commonly involved. Most of the HIV encephalitis cases are accompanied by brain atrophy. No previous study has reported symmetric increased signal intensity at the bilateral centrum semiovale without brain atrophy on diffusion weighted images in HIV encephalitis patients. Here, we report a case of this. We suggest that radiologists should consider the possibility of HIV encephalitis if there are symmetric increases in signal intensity at the bilateral centrum semiovale on diffusion weighted images of patients with a history of HIV infection.
