We are describing a case of a 14-year-old girl who developed acute cerebral infarction which was documented on diffusion-weighted magnetic resonance imaging (DWI). On detailed evaluation, diagnosis of cerebral proliferative angiopathy (CPA) was made. Incidentally, she had capillary malformation on the forehead contralateral to cerebral vascular malformation. To our knowledge, this is the first case of CPA in the literature where DWI abnormality was due to acute cerebral infarction.
