| 目的 观察深在性囊性胃炎(GCP)CT及MRI表现。方法 回顾性分析17例经手术或活检病理确诊的GCP患者,观察病灶CT及MRI表现。结果 17例GCP中,16例(16/17,94.12%)为单发、1例(1/17,5.88%)为弥漫性多发病灶;5例(5/17,29.41%)位于胃底、4例(4/17,23.53%)位于胃体,位于贲门及胃窦各3例(3/17,17.65%),1例(1/17,5.88%)位于幽门、1例(1/17,5.88%)为弥漫性分布。10例(10/17,58.82%)平扫CT表现为胃壁局部等密度增厚,增强后黏膜均匀强化。5例(5/17,29.41%)囊性为主病灶CT表现为黏膜下囊状隆起,向胃腔内生长,呈类圆形或长椭圆形等低密度,增强后黏膜呈三明治样强化;其中2例MRI表现为病灶局限于黏膜下,T1WI低信号、T2WI高信号,弥散加权成像示弥散不受限,增强模式与CT一致。2例(2/17,11.77%)囊实性病灶平扫CT表现为软组织密度,增强后呈肿块样分层强化。结论 GCP的CT及MRI表现具有一定特征性。 |

| Objective To observe CT and MRI manifestations of gastritis cystica profunda (GCP). Methods Seventeen patients with GCP confirmed by operation or biopsy pathology were enrolled, and lesions' CT and MRI manifestations were observed. Results Among 17 cases, 16 cases (16/17, 94.12%) were found with single lesion and 1 (1/17, 5.88%) with diffuse multiple lesions. The lesion located in the fundus of stomach in 5 cases (5/17, 29.41%), in the body of stomach in 4 cases (4/17, 23.53%), in the cardia and antrum of stomach each in 3 cases (3/17, 17.65%) and in the pylorus in 1 case(1/17, 5.88%), while 1 case (1/17, 5.88%) was found with diffused multiple lesions within stomach. Non-enhance CT showed local thickening of gastric wall in 10 cases (10/17, 58.82%), all were isodensities, and the mucosa uniformly enhanced in contrast enhance CT (CECT). Predominately cystic lesion in 5 cases (5/17, 29.41%) presented as submucosal cystic protrusions, and grew into the stomach cavity with circular or oblong low density in non-enhanced CT, while sandwich enhancement of mucosa was observed in CECT. Among these 5 cases (5/17, 29.41%), MRI showed lesion confined to the submucosa with low signal on T1WI and high signal on T2WI, while diffusion weighted imaging showed unrestricted diffusion, and the enhancement pattern was consistent with that of CT in 2 cases. In other 2 cases (2/17, 11.77%) with cystic-solid lesion, non-enhanced CT showed soft tissue density, while CECT showed lump-like stratified enhancement. Conclusion CT and MRI manifestations of GCP had certain characteristics. |
