Eleven lesions were very bright on DWI, with reduced ADC values.

MR imaging showed a lesion of the left internal capsule with reduced ADC, which suggests an ischemic stroke.

This case shows that very acute MS lesions may have reduced ADC on MR imaging, reflecting cytotoxic and not vasogenic edema.

At 48 h after stroke, MB significantly reduced ADC lesion and T2WI lesion volume and attenuated cerebral swelling.
