Extraordinary linear non‐enhancing brainstem leptomeningeal metastasis from lung adenocarcinoma: A case report

Abstract

Key Clinical Message In patients with lung adenocarcinoma, angiogenesis‐altering drugs can alter the appearance of leptomeningeal metastasis on magnetic resonance imaging (MRI) scans. In the ventral brainstem, this can manifest as a unique, linear, non‐enhancing T2‐hyperintense signal.
