Supratentorial and posterior fossa PML.A and B, Axial T2-weighted images (3700/150/2) show involvement of the medulla (arrow, A), right temporal lobe white matter, right thalamus, and right internal and external capsules, with mild cortical atrophy and no mass effect. Note the asymmetrical involvement of PML, with the right cerebral hemisphere affected to a much greater degree than the left. (Note also the maxillary sinus and left mastoid opacification.)fig 3. Cerebellar PML. Axial T2-weighted image (2000/80/1) shows bilateral hyperintense lesions in the cerebellar white matter (right greater than left). M. Judith Donovan Post et al.
