(A) Few cortico-subcortical hyperintense lesions in the right frontal lobe; T2-weighted (T2W). (B) Brain magnetic resonance imaging of the same patient, repeated after 1 month. T2-weighted image.

One lesion showed contrast enhancement and the findings were suggestive for PML (Figure 1A). The brain MRI performed 1 month later showed unmodified findings (Figure 1B), in absence of contrast enhancement.

(A) Hyperintense lesions in the left frontotemporal pole along with confluent juxta-cortical lesions of the white matter of the left temporal pole and homolateral insula. T2-FLAIR weighted image. (B) Further new magnetic resonance imaging performed 3 weeks later. Note the slight dimensional increase of the confluent temporal lesion. T2-FLAIR weighted image.

T2 hyperintense lesions in the left frontotemporal pole along with confluent juxta-cortical lesions of the white matter of the left temporal pole and homolateral insula, with patchy, diffuse contrast enhancement (Figure 2A). The patient did not show new neurological signs or symptoms. A further new MRI performed 3 weeks later showed a slight dimensional increase of the confluent temporal lesion (Figure 2B).
