Preferentially infratentorial localisation. A 35-year-old male diagnosed with Behçet’s disease (small intestine biopsy proven) shows in a axial FLAIR MRI at the level of the crus cerebri a heterogeneous left mesodiencephalic lesion with oedema, typically sparing the red nucleus, and in b coronal post-contrast T1-weighted MRI at the level of the pons miliary enhancement and one larger nodule. c Axial post-contrast T1-weighted MRI of a 55-year-old male diagnosed with CLIPPERS, showing miliary-enhancing nodules and slight linear enhancement along the PVS in the pons, dentate nuclei and spreading through the cerebellum and a d complete resolution of the infratentorial lesions after corticosteroid therapy
