Right hemifacial spasm, LUE task specific dystonia, rule out lesion, abnormality involving facial nerve. MRI: There are postoperative findings related to left parietal craniotomy with encephalomalacia in the superior portion of the left postcentral gyrus. There is also mild nonspecific scattered cerebral white matter T2 hyperintensity. There is no evidence of intracranial hemorrhage, mass, or acute infarct. There is no abnormal intracranial enhancement. The ventricles and basal cisterns are unchanged in size and configuration. There is no midline shift or herniation. The orbits, skull, and scalp soft tissues are grossly unremarkable. There is a retention cyst in the left frontal sinus. MRA: There is vertebrobasilar dolichoectasia and a markedly tortuous right vertebral artery that displaces the right cranial nerve 7 and 8 complex superiorly just medial to the porus acusticus. There is no evidence of significant steno-occlusive lesions or saccular aneurysms.
