摘　　要：目的探讨阑尾杯状细胞类癌的CT影像表现及特点,以提高影像诊断水平。方法回顾性分析7例阑尾杯状细胞类癌患者的临床及相关影像学资料,并复习、结合文献,探讨该罕见病的术前影像学诊断方法。结果本组研究7例患者,其中男5例,女2例,年龄30~72岁,平均52.6岁。所有患者术前均行超声及CT检查。除1例超声漏诊,1例误诊为肠系膜囊肿,其余病例超声均表现为阑尾管腔不同程度扩张,表现为管状低回声。CT表现为右下腹阑尾呈管状扩张,沿阑尾长轴方向;病灶边缘光滑,囊壁厚度均匀,未发现明显壁结节或囊壁钙化;病灶内密度均匀,CT值通常大于25HU;部分病变累及盲肠末端,部分病变周围脂肪间隙模糊并可见小淋巴结显示。所有病例均行手术,并获得病理结果。结论认识、了解阑尾杯状细胞类癌CT影像表现具有重要意义。Objective To investigate the CT imaging characteristics of appendix goblet cell carcinoma in order to improve its diagnostic level.Methods The clinical and imaging data of seven patients with appendix goblet cell carcinoma were retrospectively analyzed,and the diagnosis method of this rare disease was discussed in combination with the review of relevant literature.Results Seven patients in this group,5 males and 2 females,aged 30-72 years old,averaged 52.6 years old.Seven patients underwent ultrasound and CT examination before surgery.Except for 1 case of ultrasound,no positive lesions were found,1 case was misdiagnosed as a mesenteric cyst,and the rest of the cases were ultrasonographed with different degrees of expansion of the appendix lumen,which was manifested by tubular hypoechoic.CT shows tubular dilation of the right lower quadrant appendix,smooth edges,thin cyst wall,and uniform thickness,no obvious wall nodules or cystic wall calcifications are seen;internal density is uniform,CT values are more than 25HU;part is closely related to the cecum,and some of the surrounding fat gaps are blurred and small lymph nodes are displayed.All cases were operated on and pathological results were obtained.Conclusion It is of great significance to understand CT features of appendix goblet cell carcinoid.
