摘　　要：目的探讨胃肠道海绵状血管瘤的CT及MRI表现。方法回顾性分析经病理证实的6例胃肠道海绵状血管瘤的临床资料及影像表现。结果 6例病变中1例位于食道,5例位于乙状结肠、直肠。CT显示病变肠管管壁弥漫性增厚,近端肠管无梗阻及扩张表现,黏膜完整,肠壁及肠周脂肪间隙可见"静脉石";增强后轻到中度强化,呈缓慢渐进性强化方式,肠周可见大量迂曲扩张的血管影。MRI检查T2WI脂肪抑制序列上增厚的肠壁呈明显高信号,肠壁及肠周可见无信号"静脉石",肠周未见"流空信号",增强后与CT相仿。结论胃肠道海绵状血管瘤的CT及MRI表现有一定的特征性,可明确病变的位置、范围及肠周情况,结合临床病史,有助于提高本病诊断的准确率,协助临床治疗方案的制定。Objective To investigate the CT and MRI features of gastrointestinal cavernous hemangioma. Methods The clinical data and imaging findings of 6 cases of gastrointestinal cavernous hemangioma proved by pathology were analyzed retrospectively.Results Of 6 cases of gastrointestinal cavernous hemangioma,1 case located in esophagus,5 cases located in sigmoid colon and rectum.CT showed diffuse thickening of the wall of the diseased bowel wall,with no obstruction or dilation of the proximal bowel,intact mucosa,and "phleboliths" in the intestinal wall and perienteric fat space.After enhancement,mild to moderate enhancement was observed in a slow progressive enhancement pattern,and a large number of tortuous dilated vascular shadows were observed around the bowel.The thickened intestinal wall on T2-weighted fat-suppressed MRI images showed obvious high signal intensity.No signal "phleboliths" was observed in the intestinal wall and periintestinal region,and no "flow void signal" was observed in the periintestinal region.Conclusion The CT and MRI findings of gastrointestinal cavernous hemangioma have certain characteristics,which can identify the location,extent and periintestinal conditions of the lesion.It is helpful to improve the diagnostic accuracy of gastrointestinal cavernous hemangioma.
