MR imaging findings, histopathological specimens and gene detection of JCV-induced PML. a-d Multiple lesions in both hemispheres with hypointensity on T1 imaging and hyperintensity on T2 or FLAIR imaging; e, f Axial and sagittal contrast MR imaging revealed a large massive lesion located in the left parietal lobe with slight dotted enhancement. g, h Immediate and 24-month postoperative MR imaging. I Histopathological specimens revealed some infected cells with enlarged or bizarre-shaped nuclei, with a background of infiltration of plasma cells, lymphoid cells, and abundant macrophages. J A “High-throughput DNA Gene Detection of Pathogenic Microorganisms” confirmed the infection of JC virus
