Metastatic melanoma on Temodar. The intrinsically T1 hyperintense lesions in the bilateral cerebral hemisphere are stable to slightly decreased in size. For example, a lesion in the left occipital lobe measures 4 mm in diameter, previously also 4 mm, while a lesion in the right anterior cingulate gyrus measures 3 mm in diameter, previously 5 mm. There is no appreciable vasogenic edema associated with the lesions. There is no evidence of intracranial hemorrhage or acute infarct. The ventricles and basal cisterns are unchanged 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.
Stable to slight interval decrease in size of the brain metastases.
