Female, 62 years old, with history of brain metastases status post laser ablation to the right frontal lesion and stereotactic radiosurgery to a left occipital lesion. A partially solid and partially cystic lesion is redemonstrated within the right superior frontal gyrus. As on prior examinations, the solid component is intrinsically T1 hyperintense but does also enhance homogeneously. Although it is difficult to appreciate significant changes in this lesion when compared to the immediate prior exam, the solid nodular component of the lesion has more clearly increased in size when compared to older studies. For example, the solid component measures up to 17 mm in the axial plane on today's examination, and measured approximately 10 mm on 01/18/16. There is a mild degree of surrounding parenchymal FLAIR hyperintensity which has also slowly increased over the prior several exams.An intrinsically T1 hyperintense, enhancing nodule within the cuneus of the right occipital lobe has also increased slightly in size over prior examinations. Mild associated FLAIR hyperintensity has also become more conspicuous.A previously seen enhancing nodule within the cuneus of the left occipital lobe has clearly decreased in size. Associated FLAIR hyperintensity has also diminished.No new pathologic enhancement is observed. A small developmental venous anomaly is redemonstrated along the right postcentral gyrus. A small pineal region cyst is unchanged and likely benign. No evidence of generalized mass effect is seen. Multiple foci of nonspecific parenchymal FLAIR hyperintensity are redemonstrated without significant interval change. Ventricular size and morphology are within normal limits.
1.Slow interval growth of a lesion in the right superior frontal gyrus is noted, most evident when comparison is made over multiple prior studies.2.Similarly, slow interval growth of a lesion in the right superior occipital lobe is demonstrated.3.Interval decrease in size of a lesion in the superior left occipital lobe.4.No new lesions are detected.
