Newly diagnosed right breast cancer with axillary lymph node and supraclavicular node. There is a 4 mm diameter enhancing nodule in the right superior precentral gyrus with mild vasogenic edema. There is a 2 mm diameter nodule in the left middle frontal gyrus with mild vasogenic edema. There is no evidence of intracranial hemorrhage or acute infarct. There is scattered cerebral white matter T2 hyperintensity, which may represent chronic small vessel ischemic disease. 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, and scalp soft tissues are grossly unremarkable. There is a 27 mm diameter right maxillary alveolar cystic lesions with peripheral enhancement. There are secretions in the right maxillary and ethmoid sinuses. There are periodontal left maxillary alveolus inflammatory changes.
1. Subcentimeter lesions in the bilateral frontal lobes are compatible with metastases.2. Probable odontogenic cyst arising from the right maxillary alveolus. Dedicated maxillofacial imaging may be useful for further evaluation.
