MRI
Axial T1
Axial T1 C+ fat sat
Axial FLAIR
Axial T2
Axial SWI
Multiple intra-axial lesions centred at grey-white junction, with vasogenic edema. The lesions demonstrate intrinsic T1 hyperintensity, heterogeneous enhancement, T2/FLAIR iso/hypointensity and blooming on SWI.
The T1 and SWI signal characteristics could be due to melanin and/or blood products.
