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(2019; Volume 40,Issue 4)から、下記3論文を紹介します。

Imaging Review of New and Emerging Sinonasal Tumors and Tumor-Like Entities from the Fourth Edition of the World Health Organization Classification of Head and Neck Tumors. (AJNR 2019;40(4):584-590.)
WHO2017年新分類に登場した鼻腔副鼻腔腫瘍・腫瘍類似病変の総説です。

小児脳腫瘍でPNETがなくなり、代わりに出てきたETMRの画像所見に関しての論文です。
PNETに似てますね。
