摘要：目的：研究阑尾粘液囊肿的高频超声表现，提高对该病的认识和诊断水平。方法：回顾性分析5例经手术病理证实的阑尾粘液囊肿的高频超声表现。结果：病变均位于右下腹，其中盲肠内侧3例，盲肠后方1例，子宫右侧1例；形态圆形2例，椭圆形及囊袋状3例；壁失去正常三层形态，各层分界不清；边缘清楚、光整3例，部分边界不清1例，边界不清并与周围组织粘连1例；伴有壁钙化2例；囊内积满液性暗区，内有细小均匀光点3例，有分隔1例，囊性为主，边缘实性组织1例。结论：高频超声是阑尾粘液囊肿术前诊断及与其他病变鉴别的重要检查手段。典型高频超声表现为右下腹圆形、椭圆形及囊袋状囊性肿物，伴有或不伴有囊壁钙化。

    Abstract：Objective： To investigate the high frequency ultrasonic wave features of mucocele of the appendix,and to improve the diagnostic ability of the disease . Method： All 5 patients with mucocele of the appendix were confirmed by pathology and surgery . High frequency ultrasonic wave finding were analyzed retrospectively . Result： The high frequency ultrasonic wave demonstrated a mass of low attenuation in the right lower quadrant in all 5 cases . The masses were either spherical (n=2)or elongated (n=3) in shape . Two masses had mural calcification , and 3 had mural enhancement after contrast enhancement . The mucocele inside full liquid was a homogeneous cystic mass in 3 cases,cystic mass with internal septations in 1cases , and cystic mass with peripheral solid tissue in 1 case . Conclusion： The high frequency ultrasonic wave scan is a useful method in diagnosing mucocele of the appendix . The typical high frequency ultrasonic wave findings of appendiceal mucocele is a well-encapsulated,spherical and ellipse or elongated cystic mass in right lower quadrant,sometimes with mural calcification . ......
