Metastatic esophageal cancer with new brain metastasis. There is a lesion in the left precentral gyrus that measures up to 8 mm and contains susceptibility effect. The ventricles and basal cisterns are unchanged in size and configuration. There is no midline shift or herniation. The orbits, skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable.
Preoperative planning MRI demonstrates a subcentimeter metastasis in the left precentral gyrus.
