Figure 15.

Gastric neurogenic tumour in a 29-year-old man with epigastric pain. Inset: axial non-contrast CT shows a predominantly exophytic submucosal mass (arrow) arising from the fundus of the stomach with a speck of calcification within it (arrowhead). Axial contrast-enhanced CT at the same level demonstrates mild homogeneous enhancement within the mass (arrow). A large exogastric component and calcification are not typical features of gastric neural tumours. Enhancement is variable but usually less than that seen in GIST.
