Unusual gastric tumors and tumor-like lesions: Radiological with pathological correlation and literature review

Figure 2 Schwannoma. A 75-year-old woman presented with coffee ground vomitus. A: Pre-contrast transverse computed tomography (CT) showing a homogeneous iso-density tumor in the greater curvature of the stomach (arrow); B: Post-contrast-enhanced CT showing homogeneously moderate enhancement with a mixed (endoluminal and exophytic) growth pattern; C: Low-power photomicrograph (original magnification, × 20; HE stain) showing that the tumor retains its circumscription with lymphoid aggregate cuffing (arrow); D: The vaguely bundled spindle tumor cells were positive for S-100.
