a & b MRI of patient with HELLP syndrome A 35-year-old pregnant women at 37 weeks of gestational experiencing severe pre-eclapmsia, headache and HELLP syndrome. Brain MRI revealing grossly symmetric hyperintensities over bilateral basal ganglia, thalami (white arrows) and occipital lobes (white arrowheads) on FLAIR, but minimal hyperintensities on DWI (b), consistent with typical PRES with vasogenic edema 2 (c) MRI with multiple hyperintensity changes Brain MRI of a 39-year-old pre-eclamptic pregnant women having headache at 28 weeks of gestation. Axial FLAIR disclosed symmetric hyperintensities on bilateral medial temporal lobes (white arrows) and occipital subcortical white matters (white arrowheads), suggestive of the mild form of PRES 2 (d) MRI with micro-hemorrhage A 25-year-old pregnant woman with gestational age of 26 weeks presented with headache and hypertension up to 200/100 mmHg. A profound hypointense focus on the periventricular white matter of left occipital horn was observed by SWI, indicating of a microhemorrhage (white arrow) and a precedent change of PRES onset
