目的:探讨超声、CT增强扫描对胆囊息肉样病变的综合诊断价值。方法:收集80例经手术病理证实为胆囊息肉样病变(包括胆固醇息肉、炎性息肉、厚壁性胆囊炎、胆囊腺肌症、胆囊腺瘤、胆囊腺癌、小胆囊癌)患者的影像资料。术前均进行了超声、CT增强检查。结果:80例胆囊息肉样病变,超声、CT增强扫描全部显示恶性15例,超声确诊12例,确诊率为80.0%(12/15),漏诊3例;CT增强确诊14例,确诊率为93.3%(14/15),漏诊1例。良性65例,超声确诊55例,确诊率为84.6%(55/65),2例良性病变误诊为恶性;CT增强确诊43例,确诊率为66.2%(43/65),1例良性病变误诊为恶性。结论:超声和CT增强检查均能有效检出胆囊息肉样病变;CT增强扫描鉴别肿瘤性息肉优于超声,而超声对良性胆囊息肉样病变的病理分型明显优于CT增强扫描,二者联合应用对胆囊息肉样病变的诊断更可靠。
Objective: To investigate the value of ultrasound and CT in the diagnosis of polypoid lesions of gallbladder. Methods: Eighty patients with pathologically confirmed gallbladder polyposis lesions (including polyps of cholesterol, inflammatory polyp, thick cholecystitis, cholecystacarcoma, gallbladder adenoma, gallbladder adenocarcinoma, small gallbladder carcinoma) were collected. . Preoperative ultrasound were performed, CT enhanced examination. Results: 80 cases of gallbladder polypoid lesions, ultrasound and CT enhanced scan all showed malignant in 15 cases, ultrasound confirmed in 12 cases, the diagnosis rate was 80.0% (12/15), missed diagnosis in 3 cases; CT enhanced diagnosis of 14 cases, the diagnosis rate was 93.3 % (14/15), missed diagnosis in 1 case. 65 cases were diagnosed as benign and 55 cases were diagnosed by ultrasound. The diagnosis rate was 84.6% (55/65). Two cases of benign lesions were misdiagnosed as malignant. Forty cases were diagnosed by CT with a definite diagnosis rate of 66.2% (43/65) and one case of benign lesions was misdiagnosed To be vicious. Conclusion: Ultrasound and CT enhanced examination can effectively detect polypoid lesions of gallbladder; CT enhanced scan to differentiate tumor polyp more than ultrasound, and ultrasound in benign gallbladder polypoid lesions pathological type was significantly better than CT enhanced scan, the two combined The diagnosis of polypoid lesions of the gallbladder is more reliable.
