Metastatic breast cancer. There is an enhancing extra-axial parasagittal right frontal convexity lesion that measures 6 x 8 mm in cross-section, without mass effect upon the underlying brain. There is no evidence of intracranial hemorrhage or acute infarct. The brain parenchyma and pituitary gland appear unremarkable. There is no abnormal intracranial 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.
A small extra-axial right frontal convexity lesion likely represents a meningioma versus less likely a metastasis. Otherwise, there is no evidence of intraparenchymal metastases.
