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(2020; Volume 41,Issue 10)から、下記4論文を紹介します。
「Neuroimaging in Zoonotic Outbreaks Affecting the Central Nervous System: Are We Fighting the Last War?. (AJNR 2020;41(10):1760-1767.)」
中枢神経系を傷害する人獣共通感染症の総説。蝙蝠、蚊、ダニ、が怖い。
Table 2がおすすめです。
Organisms that have crossed the species barrier from animals to humans include viruses such as Hendra, Nipah, Severe Acute Respiratory Syndrome, and influenza, as well as bacteria and others. Brain CT and MR imaging findings have included cortical abnormalities, microinfarction in the white matter, large-vessel occlusion, and features of meningitis.
「Exophytic Lumbar Vertebral Body Mass in an Adult with Back Pain. (AJNR 2020;41(10):1786-1790.)」
外方発育した脊索腫 Chordomaの症例。
「Imaging Features of Acute Encephalopathy in Patients with COVID-19: A Case Series. (AJNR 2020;41(10):1804-1808.)」
本号では、本論文以外もCOVID-19関連中枢神経系疾患が盛り沢山です。
MR features include leukoencephalopathy, diffusion restriction that involves the GM and WM, microhemorrhages, and leptomeningitis.
「Open AccessParaspinal Myositis in Patients with COVID-19 Infection. (AJNR 2020;41(5):1949-1952.)」
画像を見るときは、外から隅々まで見ないといけませんね。
非常に教訓的な症例です。
