Abstract

The hippocampus is one of the most metabolically active regions of the brain; therefore, it may be affected by various acute disorders. This study aimed to introduce and categorize various acute conditions that can involve the hippocampus and explain the findings of MRI, especially diffusion-weighted imaging (DWI). Acute hippocampal disorders are divided into six categories: infection, inflammation, metabolic, ischemic, traumatic, and miscellaneous. In this study, patients were retrospectively reviewed based on clinical findings and MRI, especially DWI. All diseases had been confirmed clinically or pathologically. Many acute hippocampal disorders overlap with the clinical manifestations. Thus, it is necessary to categorize acute hippocampal lesions and understand their specific imaging findings for differential diagnosis.

해마는 뇌에서 가장 대사가 활발한 부위 중 하나이다. 그러므로 해마는 다양한 급성기 질환으로부터 영향을 받을 수 있다. 이 연구의 목적은 해마와 관련된 다양한 질환들을 소개 및 분류하며 특히 확산강조영상을 중심으로 자기공명영상 소견에 대해 설명하는 것이다. 급성기 해마 질환은 감염, 염증, 대사성, 허혈성, 외상성 그리고 기타 총 6가지로 분류하였다. 환자들은 임상적 소견 그리고 확산강조영상 중심의 자기공명영상을 토대로 후향적으로 검토되었다. 모든 질환들은 임상적 또는 병리학적으로 진단되었다. 급성기 해마 질환들은 임상 양상이 겹치는 경우가 많다. 그러므로 감별 진단을 위해서 급성기 해마 질환들을 분류하고 각각의 특징적인 영상 소견을 이해하는 것이 중요하다.
