This appears stable compared to prior exam.There is redemonstration of multiple punctate foci of signal loss on susceptibility weighted imaging the thalami and brainstem. These have not changed. One in the pons and another in the right thalamus are associated with punctate contrast enhancement. These too may be associated with dilated vascular structures. There is stable.Normal vascular flow voids are present in the distal carotid and vertebral arteries, the basilar artery and the proximal anterior, middle and posterior cerebral arteries as well as the internal cerebral veins and superior sagittal sinus.The visualized portions of the paranasal sinuses demonstrate couple mucous retention cysts..
