<論文紹介:AJNR 2021;42(9):1610-1614.他>

神経放射線診断学において、American Journal of Neuroradiology (AJNR)がと ても役立ちますよ、ということを以前お話ししましたが、最新号「September 01, 2021; Volume 42,Issue 9」から、下記3論文を紹介します。
いずれも丁寧に画像を見ることからの気づき、の内容です。
本号は、紹介論文以外にも盛り沢山で他の論文もおすすめです。

Absence of Meckel Cave: A Rare Cause of Trigeminal Neuralgia. (AJNR 2021;42(9):1610-1614.)
三叉神経痛患者さんにおいて、Meckel caveを同定できないことがある、という お話。
Seven patients (100%) had ipsilateral trigeminal neuralgia and ipsilateral trigeminal nerve atrophy, suggesting an association between absence of Meckel cave and trigeminal neuralgia.

Time Course and Clinical Correlates of Retinal Diffusion Restrictions in Acute Central Retinal Artery Occlusion. (AJNR 2021;42(9):1661-1666.)
