Female, 32 years old, history of neuroblastoma, yearly follow-up to evaluate for meningiomas. Redemonstrated are findings secondary to bilateral frontal and left temporal craniotomy. The bilateral frontal lobes remain encephalomalacic and hemosiderin-stained similar to the prior examination.A nodular enhancing lesion along the left aspect of the posterior interhemispheric falx is unchanged in size measuring up to 8 mm in thickness. A nodular enhancing lesion along the right dorsum sella is also unchanged measuring up to 6 mm. Thin plaque-like enhancement along the right frontal convexity is unchanged as well.An enhancing lesion within the right frontal bone measures up to 20 mm in length and is slightly increased in size when compared to prior examinations where it measured 15 or 16 mm. It is more noticeably increased in size when compared to more remote examinations dating back to 2006.No new enhancing lesions are identified. No significant parenchymal edema is detected. Ex vacuo dilatation of the frontal horns is unchanged. Ventricles are otherwise unremarkable. Scattered foci of parenchymal susceptibility effect are unchanged and likely related to prior radiotherapy.
1.Redemonstration of extensive postoperative and treatment related findings. Hemosiderin stained encephalomalacia of the bilateral frontal lobes is unchanged.2.Multiple dural based enhancing lesions show no significant interval change in size.3.A lesion centered on the right frontal bone shows a mild interval increase in size, most notable when comparison is made to examinations from several years ago. The etiology and clinical significance of this finding are uncertain.
