今月の特集2 神経・筋疾患の超音波検査

慢性炎症性脱髄性多発根神経炎（CIDP）における超音波検査

著者： 北國圭一¹

所属機関： ¹帝京大学脳神経内科

ページ範囲：P.870 - P.877

Point

●超音波検査の慢性炎症性脱髄性多発根神経炎（CIDP）への臨床応用は著しい発展を遂げており，神経超音波は最新のEAN/PNS（European Academy of Neurology/Peripheral Nerve Society）の診療ガイドラインにも診断補助ツールとして取り入れられている．

●CIDPの神経超音波では末梢神経の遠位〜近位，さらに神経根も含む広範な領域に神経/神経束腫大が認められる．

●CIDPでみられる神経腫大は部位ごとにばらつきがあり，この特徴が他の脱髄性ニューロパチーとの鑑別診断に有用である．

●神経超音波・筋超音波における神経・筋の形態異常がCIDPの病態，治療反応性や予後の推定に役立つ可能性も報告されている．
