摘　　要：非直接侵犯性胃转移癌是一种少见的胃肠道恶性肿瘤,缺乏特异的临床症状,极易被忽视或误诊.虽然其多层螺旋CT(multisliecs helieal CT,MSCT)表现多样,但具有一定的特征性,可与胃间质瘤、原发性胃癌相鉴别.因此,对伴有消化系症状的恶性肿瘤患者,影像医生应提高对本病的警惕和认识,结合病史,仔细识别其MSCT征象,可提示诊断.Gastric metastases not resulting from direct invasion are rare.Clinically,these patients present with nonspecific symptoms,which easily lead to missed diagnosis or misdiagnosis.MSCT findings of the disease may vary but often have characteristic features,different from those of gastric stromal tumors and primary gastric cancer.Thus,for cancer patients with gastrointestinal symptoms,medical imaging workers should improve the recognition and vigilance of the disease.Careful identification of the characteristic MSCT findings combined with the clinical history can help provide a suggestive diagnosis.
