画像診断総説雑誌として、「Insights into Imaging」誌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ね。

最新号(Volume 9, Issue 5, October 2018)が久しぶりに盛り沢山なのですが、下記の教育的な2論文を紹介します。

Fasciae of the musculoskeletal system: normal anatomy and MR patterns of involvement in autoimmune diseases.(Insights into Imaging 2018;9(5):761–771.)

画像上、筋膜に異常を認める病態に出会うことが結構ありますよね。

• The fascial system is a three-dimensional continuum of connective tissues.
• MR patterns of fascial involvement in autoimmune diseases reflect the complex anatomy of the fasciae of the musculoskeletal system.

Magnetic resonance imaging of arterial stroke mimics: a pictorial review.(Insights into Imaging 2018;9(5):815–831.)

脳脊髄液リンパ球増加症候群による一過性の頭痛と神経学的欠損症候群(HaNDL)という概念を初めて知りました。
Headaches with associated neurological deficits and lymphocytosis (HaNDL) are characterised by temporary recurrent neurological deficits, moderate to severe headache, cerebrospinal fluid lymphocytosis, elevated protein and increased opening pressure. Migraine aura and HaNDL may share a common pathophysiological pathway, resulting in similar imaging findings, namely, no altered diffusion-weighted images, no arterial occlusion, but hypoperfusion in more than one arterial territory.
Additionally, leptomeningeal hyperintensity on FLAIR images with corresponding enhancement on post-contrast T1-WI, certainly related to lymphocytic meningitis, are suggestive MRI features of HaNDL in this clinical setting. Of course, HaNDL remains a diagnosis of exclusion, but MRI is useful for early distinction between this syndrome and a stroke.

上述と関連して、最近、国際頭痛分類の第3版がでましたね。
ベータ版が、下記からダウンロードできますよ。
