目的:探讨深在性囊性胃炎（GCP）的CT影像特征及临床特点，提高对该病的诊断水平。方法:回顾性搜集2015年6月至2019年8月郑州大学第一附属医院经病理确诊的GCP患者的临床及CT影像资料。共纳入9例患者，男3例，女6例，年龄44~66（59±7）岁。所有患者均行腹部CT平扫及增强扫描，分析并总结病灶的部位、大小、形态、边缘、密度、强化方式及强化程度。结果:9例GCP患者，病灶位于胃底3例，胃窦3例，贲门、胃体小弯侧、胃体大弯侧各1例；2例病灶以实性成分为主，7例病灶以囊性成分为主；CT表现为胃壁增厚3例，类圆形或圆形团块影突向胃腔6例；增强扫描动脉期病灶实性成分明显强化6例、中度强化3例，病灶肌层轻度强化5例、中度强化4例；静脉期病灶实性成分渐进型明显强化6例、中度强化3例；病灶肌层强化不明显5例、渐进性中度强化4例；囊肿表面衬有完整的黏膜层7例、黏膜层欠光整2例。结论:在准确定位的基础上，CT检查可提供GCP病变大小、形态、内部结构及病变周围情况等信息，对GCP的诊断具有重要价值。“,”Objective:To explore the CT imaging and clinical features of gastritis cystica profunda (GCP) and improve the level of diagnosis.Methods:From June 2015 to August 2019, the clinical and CT imaging data of 9 GCP patients confirmed by pathology in the First Affiliated Hospital of Zhengzhou University were retrospectively collected. These 9 GCP patients included 3 male and 6 female, aged from 44 to 66 years, with an avereage age of (59±7) years. All the 9 patients underwent plain and enhanced abdominal CT scan. The location, shape, size, margin, density, enhancement pattern and enhancement degree of the lesions were analyzed and summarized.Results:The lesions are more common in gastric antrum (3 cases) and gastric fundus (3 cases). CT imaging showed thickening gastric wall thickening in 3 cases, circular ovoid or circular mass shadow protruding into the gastric cavity in 6 cases. Solid components were dominant in 2 cases and cystic components were dominant in 7 cases. In arterial phase, solid components showed significantly enhancement in 6 cases and moderate enhancement in 3 cases, while muscle layer of lesions were characterized by mild enhancement in 5 cases and moderate enhancement in 4 cases. In venous phase, solid components illustrated as significantly enhancement in 6 cases with progressive pattern and moderate enhancement in 3 cases, while the muscle layer of lesions were featured as progressive moderate enhancement in 4 cases and there is no significant enhancement in the rest 5 cases whose enhancement degree were similar to that of normal gastric wall. Additionally, the surface of the cyst covered with intact mucosa in 7 cases and in other 2 cases without complete mucosa.Conclusion:On the basis of accurate localization, CT scan could provide rich information including size, shape, internal structure and state around the lesion, which is of great value for the diagnosis of GCP.
