Female patient aged 64 years old presented with hemiparesis and difficulty in speech. MRI brain showed left parietal acute infarction (short arrow) showing low signal intensity in T1WI (a) and high signal intensity in T2WI and FLAIR sequences (b, c) with restricted diffusion, hyperintense SI in diffusion (d), and hypointense SI in ADC (e), and no blooming effect in SWI (f) denoting non-hemorrhagic infarction together with another left basal ganglion (body of caudate) (long arrow) acute infarction with small dots of microhemorrhage seen inside by SWI (f) confirmed by low signal intensity in filter phase (g) denoting hemorrhagic infarction that was overlooked by T1WI
