The multiple extra-axial lesions are again demonstrated, showing iso-signal on T1 and high signal on T2 compared to the adjacent brain, keeping the vivid contrast enhancement and, some of them, with a necrotic hypoattenuating central area. The largest one arises from the left sphenoid wing in the left middle cranial fossa and promotes mass effect with compression over the left lateral ventricle and mild midline shift to the right, regional oedema, as well as left transtentorial herniation downward.
The second largest mass, arising from the parietal bone on the left demonstrates increased T2 signal and facilitated diffusion on ADC.
Conclusion: The lesions are in keeping with multiple meningiomas which are probably secondary to prior radiotherapy treatment.
