摘要
目的:总结原发性胃淋巴瘤的CT表现及误诊原因,提高其CT诊断水平.方法:回顾性分析经病理确诊的22例原发性胃淋巴瘤的CT表现及其中13例误诊原因.结果:病变累及胃窦、体及底部2个或3个部位20例,仅累及1个部位2例.CT表现为胃壁增厚(6mm-60mm)21例,仅表现为多发结节1例(4.5%).伴有肿块2例,多发溃疡8例.胃壁黏膜线破坏16例,黏膜线完整11例.胃壁增厚的21例中6例既有较薄的胃壁分层强化,又有较厚的胃壁黏膜破坏,胃腔可扩张、无明显狭窄15例.CT误诊为浸润型胃癌11例,间质瘤1例,将多发结节误诊为正常黏膜1例.结论:原发性胃淋巴瘤的CT表现为多累及2个或3个部位的胃壁增厚,初期因黏膜完整胃壁呈分层强化,胃腔可扩张或无狭窄,CT易误诊为浸润型胃癌.
AIM： To improve the computed tomography （CT） diagnosis of primary gastric lymphoma by describing its CT presentations and possible reasons for misdiagnosis.
METHODS： CT scans were retrospectively reviewed in 22 patients with pathologically confirmed primary gastric lymphoma, and 13 misdiagnosis cases were analyzed for its possible causes.
RESULTS： Primary gastric lymphoma involved two or three sites of the gastric antrum, gastric body and fundus of stomach in 20 pat/ents and only one site in 2 patients. CT findings showed thickened gastric wall in 21 patients （6 mm-60 mm） and gastric multiple nodules in one patient. Among the 21 patients with thickened gastric wall, 2 cases were found to have gastric masses, 8 cases multiple ulcers, 16 cases destructed mucosal lining, 11 cases intact mucosal line. Six of the 21 patients with thickened gastric wall presented with stratified gastric layers and mucosal damage. In the remaining fifteen of the 22 patients, the stomach remained distensible without significant luminal narrowing. Primary gastric lymphoma was misdiagnosed as infiltrative gastric carcinoma in eleven patients, as stromal tumor in one patient and as normal mucosa in one patient.
CONCLUSION： Primary gastric lymphoma include gastric wall thickening with two or three-site involvement, intact mucosal line with stratified mural enhancement in the initial stage, distensible stomach without significant luminal narrowing. Primary gastric lymphoma is easily misdiagnosed as infiltrative gastric carcinoma using CT.
