高频超声对阑尾粘液囊肿的诊断评价

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7例经手术病理证实的阑尾粘液囊肿的高频超声影像表现.结果 病变均位于右下腹,其中盲肠内侧4例,盲肠后方1例,子宫右侧2例;形态圆形2例,椭圆形及囊袋状5例;失去正常三层形态,各层分界不清,边缘清楚,回声增强3例,部分边界不清2例,边界不清并与周围组织粘连2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 高频超声在阑尾粘液囊肿的术前诊断及与其他病变鉴别诊断中具有较大价值.

Evaluation of mucocele of the appendix:high frequency ultrasonic wave

Objective To investigate the high frequency ultrasonic wave features of mucocele of the appendix,and to improve the diagnostic ability of the disease. Methods All 7 patients with mucocele of the appendix were confirmed by pathology and surgery. High frequency ultrasonic wave findings were analyzed retrospectively. Resuits The high frequency wltrasonic wave demonstrated a mass of low attenuation in the right lower quadrant in all 7 cases. The masses were either spherical( n = 2) or elongated ( n = 5) in shape. Two masses had mural calcification,and 4 had mural enhancement after contrast enhancement. The mueocele inside full liquid was a homogeneous cystic mass in 3 cases,cystic mass with internal septations in 1 case,and cystic mass with peripheral solid tissue in 1 case.Conclusion The high frequency ultrasonic wave scan is a useful method in differential diagnosis mucocele of the appendix.
