腸系膜囊腫－3例報告

腸系膜囊腫為源於腸系膜的良性囊狀腫瘤，臨床上非常罕見。三軍總醫院報告3例如腹部超音波掃描與電腦斷層攝影診斷為腸系膜囊腫(mesenteric cyst)病例，後經臨床與病理學證實。腸系膜囊腫於超音波掃描呈現－薄壁、周壁平滑完整的無回音腫塊，後壁有回音加強現象，其內常出現隔膜(internal septa)電腦斷層檢查呈現腹腔內低密度（水樣密度）、而周壁完整的水囊狀腫塊，將周圍腸道推移。本文依據此3例之位置、形狀、內隔膜與病理學之結果、分析電腦斷層掃描術與超音波術的優、劣，認為兩者配合使用、具相輔相成之效果，而可避免進一步侵入性診斷方法的使用。

並列摘要

Mesenteric cyst is a rare benign intraabdominal neoplasm which is originated from mesentery. Three cases were collected in our hospital from 1985 to 1989 to correlate the ultrasound and CT findings with clinical and pathological diagnosis. Ultrascopically the mesenteric cysts are typically smooth-walled, hypoechoic or echo-free, round mass with increased sound reflection on the posterior wall, but on CT, they are cystic masses of low attenuation usually displacing the bowel loops. Mesenteric cysts may be multi-locular in appearance, but usually single in number. Since the diagnosis may be accurately made by CT and ultrasound before operation, other invasive diagnostic procedures can be therefore obviated.
