New left-sided 7th nerve palsy, history of DLBCL, melanoma, breast cancer. There is new diffuse left facial nerve enhancement. There is no evidence of intracranial hemorrhage, mass, or acute infarct. There are a few nonspecific punctate foci of T2 hyperintensity within the cerebral white matter. The ventricles and basal cisterns are unchanged in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable. There are bilateral lens implants.
New diffuse left facial nerve enhancement is suggestive of Bell's palsy rather than neoplastic involvement and there is otherwise no evidence of brain metastases.
