Among submucosal tumors ( SMT ), gastric glomus tumors are rare vascular tumors, and only a few cases where glomus tumors have been differentiated from other mesenchymal tumors by endoscopic ultrasonography ( EUS ) or computed tomography ( CT ) have been reported. In this case series, we aimed to analyze the EUS and CT characteristics of gastric glomus tumors. Seven patients with gastric glomus tumors were retrospectively enrolled in this study. EUS showed that all the tumors were located in the fourth EUS layer (muscularis propria) and had distinct borders. The tumors had a heterogeneous appearance with either hypo‐ or hyperechogenicity, and all the tumors except one had the characteristic peripheral halo around them. On CT scans,all the tumors appeared as well‐defined SMT with a clear margin and showed the same characteristics in the different phases of CT . During dynamic contrast‐enhanced CT , the tumors showed strong enhancement in the arterial phase and prolonged enhancement in the delayed phase. This case series shows the characteristic EUS findings and the distinguishing features of CT scans for gastric glomus tumors; these findings will help in differentiating gastric glomus tumors from other SMT .
