脳卒中

Stroke

ほとんどの脳卒中の症例においてその診断までの道筋は直線的で判断に迷うことはない。しかし，脳卒中を模倣する神経症状を示す脳卒中以外の疾患（脳卒中ミミック）と脳卒中以外の疾患を示唆する非典型的な症状を示す脳卒中（脳卒中カメレオン）が存在する。2例の症例提示を行い，脳卒中ミミックと脳卒中カメレオンについて概説する。これらを同定するためには詳細な病歴聴取，包括的な神経学的診察，適切な画像診断が重要である。

Abstract

The path to the diagnosis of strokes is straightforward and unquestionable in most cases. In the era of interventional stroke therapies, which have potential adverse effects, an accurate diagnosis is needed for. However, there are non-cerebrovascular diseases exhibiting neurological symptoms that simulate strokes (stroke mimics), and strokes exhibiting atypical or uncommon symptoms that suggest diseases other than strokes (stroke chameleons). This article presents two cases to outline stroke mimics and stroke chameleons. Detailed history taking, comprehensive neurological examination, and appropriate imaging studies are important to identify them.
