Fig. 1From: Neurosyphilis with a rare magnetic resonance imaging pattern confirmed by metagenomic next-generation sequencing: a case reportInitial and follow-up brain MRI findings. A–C Axial FLAIR images showed hyperintensities in bilateral medial and anterior temporal lobes, insula, right pulvinar of the thalami, precuneus, frontal and temporo-occipital lobes. D T1-contrast-enhanced MRI showed leptomeningeal enhancement in the right temporo-occipital region. E–G Post-treatment FLAIR images on 16th day of admission revealed marked improvement in the previously identified bilateral temporal, insula, precuneus, frontal and temporo-occipital hyperintensities. H Repeat gadolinium-enhanced MRI demonstrated disappearance of leptomeningeal contrast enhancement. The arrows indicated the lesionsBack to article page
