Fig. 3From: A human T-lymphotropic virus-1 carrier who developed progressive multifocal leukoencephalopathy following immunotherapy for sarcoidosis: a case reportBrain magnetic resonance imaging after neurological deterioration. Brain magnetic resonance imaging showed an enlargement of the left frontal lobe lesion with hyperintensity in fluid-attenuated inversion recovery imaging (A), diffusion-weighted imaging (B), T2-weighted image (C, inset), and apparent diffusion coefficient mapping (D) with a “milky way appearance” (arrow). This lesion still lacked gadolinium enhancement (E) with “milky way appearance” in post-gadolinium enhancement (E, inset)Back to article page
