Abstract Objective: To investgate and analyse the clinical characteristics and the CT imaging features of the gastric glomus tumors. Methods: Clinical characteristics and the imaging features of seven cases proved pathologically were analyzed retrospectively. The location, size, quantity, shape, margin, growth pattern, gastric mucosa, and the adjacent gastric wall were evaluated. The CT values of each period after enhancement were detected. Results: The lesions of six cases were distributed in gastric antrum and one case was in the junction of gastric antrum and greater curvature, with the size within 3 cm. Six cases were internal cavity growth and one internal and external cavity mixed growth. All cases manifested homogeneous density in CT plain scan, without hemorrhage, necrosis and cystic degeneration, calcification was found in one case. Five cases showed peripheral patched shaped enhancement in arterial phase, 1 case showed gross disordered vessel inside the tumor. A significant enhancement reached the peak in portal vein phase, CT values were 139.25 HU, 132.42 HU, 146.53 HU, 140.36 HU, 135.16 HU respectively, and continued to strengthen in the delay phase. Two cases reached enhancement peak in arterial phase were 138.67 HU and 148.36 HU, continuously and homogeneously enhanced in the portal vein phase but weakened in delay phase. All cases were without distance and lymphnodes metastasis. Conclusion: Gastric glomus toumor has a specific pathogenetic location and age of onset, typically presents as a benign and hypervascular tumor with a obvious and homogeneous enhancement pattern. The peak CT value of enhancement is similar to the abdominal aorta.
