History of metastatic breast cancer with syncope. There is no evidence of acute infarction. There are no enhancing lesions in the brain, brainstem, or cerebellum. However, there is patchy white matter T2 hyperintensity in the bilateral peritrigonal regions. The ventricles sulci are mildly prominent diffusely. There is also dilatation of the bilateral Meckel caves, left greater than right, and the pituitary gland is mildly flattened. There is a subcentimeter calcified mass along the left inferior frontal convexity. 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 metastasis, hemorrhage, or acute infarct. 2) Nonspecific white matter abnormality in the bilateral peritrigonal regions may be related to prior therapy.3) Mild flattening of the pituitary gland and bilateral enlargement of the Meckel caves may indicate underlying increased intracranial pressure and can be associated with the uncommon Usher syndrome.4) A subcentimeter calcified mass along the left inferior frontal convexity may represent a meningioma or osteoma, for example.
