From: Meningioma with ring enhancement on MRI: a rare case report

Fig. 1

Head CT showed an abnormal left frontal-parietal hypodense lesion (a). T1 (b), T2 (c) and T2-FLAIR (d) showing lesions that appeared iso- to hypointense on T1WI and iso- to hyperintense on T2WI. Signal hyperintensity was present in the surrounding brain on T2WI and fluid attenuated inversion recovery sequences, consistent with mild oedema. On axial enhanced T1 (e), sagittal (f) and coronal (g) ring enhancement was seen with a slightly thickened cystic wall and dural tail sign. Microscopic examination (h) confirmed fibrous meningioma with extensive central degeneration and necrosis of central tumour cells (haematoxylin/eosin [H&E]). Scale bar: 100 ┬Ám
