Female, 61 years old, with history of metastatic melanoma and brain metastases. Again seen is evidence of a treated lesion within the right superior frontal gyrus. The lesion is mildly hemosiderin stained with an irregular area of internal enhancement measuring up to 9 mm in diameter, previously 10 mm. Internally, the lesion has become predominantly T2 bright and FLAIR suppressing compatible with cystic degeneration. Minimal surrounding FLAIR hyperintensity compatible with gliosis is unchanged.A 3-mm enhancing focus within the left occipital lobe is unchanged in size. This lesion causes no significant edema or mass effect.No new enhancing lesions are detected. A developmental venous anomaly is present in the right precentral gyrus. Scattered nonspecific T2 hyperintense white matter lesions are not significantly changed. Ventricular size and morphology are normal.
1.A treated lesion in the right superior frontal gyrus shows stable to slightly reduced internal enhancement and no other evidence to suggest lesion growth.2.A small enhancing focus in the left occipital lobe is also unchanged.3.No new intracranial lesions are seen.
