NSCLC treated with CyberKnife, altered mental status since hospitalization for esophagitis and esophageal stent placement, known meningioma, new right more than left upper extremity tremor, right lower extremity tremor, and flat affect. There is no evidence of intracranial hemorrhage or acute infarct. The brain parenchyma and pituitary gland appear unremarkable. There is a subcentimeter extra-axial enhancing lesion overlying the inferior left temporal convexity. There is no abnormal intraparenchymal enhancement. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits, skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable.
1. No evidence of intracranial hemorrhage or acute infarct. 2. Unchanged subcentimeter presumed meningioma overlying the inferior left temporal convexity, but otherwise no evidence of intracranial metastases.
