MRI
Leptomeningeal and dural enhancement over both upper frontoparietal convexities, especially on the right side. These are associated with sulcal hyperintensity and subtle cortical signal abnormality in the FLAIR sequences, in the upper frontal lobes, near the vertex.
Additionally, there is a mild increase in the degree of diffusion restriction on DWI of both upper frontoparietal convexities, especially in the right side. The findings were suggestive of meningoencephalitis.
