Female, 64 years old, with history of brain metastases status post surgery and radiotherapy. A small right frontal resection cavity is redemonstrated without significant interval change in size or morphology. The degree of T2 hyperintensity surrounding the cavity is also unchanged. At most there may be minimal peripheral enhancement surrounding cavity but no concerning enhancement is demonstrated and the findings are unchanged.An enhancing lesion adjacent to the right ventricular trigone is redemonstrated showing a mild interval increase in size, now measuring 10 mm in diameter, previously 8 mm. Degree of surrounding T2 hyperintensity is also mildly increased. Nevertheless, there is no significant associated mass effect.A punctate focus of enhancement just below the left frontal horn has not significantly changed. However, a focus of enhancement in the left inferior temporal lobe has slightly increased in size now measuring 7 mm, previously 4 mm.No entirely new lesions are seen. No significant generalized mass effect is detected. The ventricles remain stable in size and morphology. No evidence of acute intracranial hemorrhage is noted.
1.No change in the appearance of the right frontal resection cavity to suggest recurrent or progressive disease.2.Mild interval increase in size of enhancing lesions in the right peritrigonal region and in the left inferior cerebellum. 3.A punctate enhancing lesion adjacent to the left frontal horn has not significantly changed.
