神経放射線診断学において、Neuroradiology 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(Volume 66, Issue 3 March 2024)から、下記3論文を紹介します。
「Postoperative disappearance of leptomeningeal enhancement around the brainstem in glioblastoma. (Neuroradiology 2024;66(3):325–332.)」
素晴らしい観察と気づきの論文。大脳深部の大きな神経膠芽腫症例において、大脳脚間を含めた脳幹表面の髄軟膜増強を認めることがあるが、これは髄膜播種を必ずしも示唆しているのではない、というお話。
「Delayed leukoencephalopathy following non-coil embolization flow diverter stent deployment for an intracranial aneur. (Neuroradiology 2024;66(3):427–429.)」
フローダイバーター留置による遅発性白質脳症の症例。
「Pediatric nasal chondromesenchymal hamartomas: a case series. (Neuroradiology 2024;66(3):437–441.)」
Nasal chondromesenchymal hamartomas (NCMH) are predominantly benign tumors of the sinonasal tract, typically associated with DICER1 pathogenic variants and most commonly affecting pediatric population.
They may mimic aggressive behavior on imaging; therefore, awareness of this pathology is important.
