Multiplanar reconstructions, however, did reveal a 1.7 cm well marginated solitary markedly enhancing mass in the gastric antrum (Figure 1).
Standard axial image from the contrast enhance MDCT does show the antral lesion in retrospect (arrow). However, the radiologist did not note this on the initial interpretation.

Retrospectively, the mass was found on axial CT images to display dense homogeneous enhancement in the arterial phase which persisted to the delayed phase (Figure 2).
(a) High-magnification hematoxylin (x100) and eosin stained section that demonstrates a fragment of smooth muscle containing infiltrating uniform cells arranged around blood vessels (arrows) and (b) positive immunohistochemical stain for actin which are supportive of a diagnosis of gastric glomus tumor.
