T1-weighted images showing intense contrast enhancement. This small mass appeared to be adherent to the dura mater with a dural tail sign [Figure 1]. The appearance suggested a convexity meningioma.
Histological examination showed a multilobulated lesion (b) composed of sinusoidal vascular spaces of various sizes lined with a single layer of endothelial cells (a and c). These vascular spaces are separated by fibrous connective tissue (a). H and E, x4 (a); H and E, x10 (b); H and E, x40 (c)
