Figure 1
(A,B) T2 axial and sagittal sequences showing a heterogeneously hyperintense T2 mass in the sinonasal region with extra-axial intracranial extension (arrows). Low-insensity foci were seen with which were attributable to calcifications or foci of haemorrhage. (C,D) The mass shows intense enhancement with areas of cystic change (arrowhead in C). Dumbbell shape of the mass was thought to be characteristic of esthesioneuroblastoma.

(A) Low power view showing hypo and hypocellular arrangement, (B) degenerative atypia, arrow pointing to nuclear atypia, (C) verocay body formation arrow pointing to nuclear palisade, (D) S-100 immunostaining. Features are consistent with schwannoma.
