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(June 01, 2021; Volume 42,Issue 6)から、下記3論文を紹介します。

Brain and Lung Imaging Correlation in Patients with COVID-19: Could the Severity of Lung Disease Reflect the Prevalence of Acute Abnormalities on Neuroimaging? A Global Multicenter Observational Study. (AJNR 2021;42(6):1008-1016.)
多岐にわたるCOVID-19関連の神経放射線画像の復習に役立ちます。
TIPIC (Transient Perivascular Inflammation of the Carotid artery syndrome, Carotidynia)も生じるそうです。本当に何でもありですね。

Clinical Features of Cytotoxic Lesions of the Corpus Callosum Associated with Aneurysmal Subarachnoid Hemorrhage. (AJNR 2021;42(6):1046-1051.)
この所見は、以前からそうではないかと思っていました。
結構あるもんですね。日本発。
Cytotoxic lesions of the corpus callosum appear at a frequency of 12.7% in patients with aneurysmal SAH. Cytotoxic lesions of the corpus callosum associated with SAH take several days to appear and subsequently resolve within about a month.

Neuroimaging Features of Ectopic Cerebellar Tissue: A Case Series Study of a Rare Entity. (AJNR 2021;42(6):1167-1173.)
珍しい異所性小脳組織の画像診断です。
Ectopic cerebellar tissue was infratentorial in 6/7 patients and supratentorial in 1/7 patients. All infratentorial ectopic cerebellar tissue was connected with the brain stem or cerebellum. MR imaging signal intensity was identical to the cerebellar gray and white matter signal intensity on all MR imaging sequences in all cases.
