Imaging, endoscopy, and pathologic findings of primary gastritis cystica polyposa: description of a rare entity in a small case series

Abstract

Primary GCP has relatively particular endoscopy features, which can be accurately diagnosed by gastroscopy when the lesion is small. But endoscopy has its limitations in the diagnosis and differentiation for some large lesions. In contrast to gastroscopy and gastroscopic ultrasound, CT or MRI provides more information about both the gastric wall and the extragastric extent of the disease, which is more helpful for differential diagnosis and surgical planning of GCP before operation.
