Left parietal lesion for stability. There is no evidence of intracranial hemorrhage, mass, or acute infarct. There are scattered areas of high T2 signal in the cerebral white matter bilaterally, without associated enhancement, which may represent chronic microvascular disease. 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. There is an enhancing lesion in the left parietal skull that measures up to 10 mm, which is unchanged. The orbits, mastoid air cells, and scalp soft tissues are grossly unremarkable. There are several paranasal sinus retention cysts.
1. No evidence of brain metastases. 2. An enhancing lesion in the left parietal skull that measures up to 10 mm may represent a metastasis, but is unchanged in size.
