卵巢肿块的CT诊断

CT diagnosis of ovary masses

目的探讨卵巢肿块的CT表现和诊断价值。方法回顾性分析96例卵巢肿块的临床及CT表现,患者年龄15岁～80 岁,平均47岁。CT检查包括平扫和增强扫描,层厚、层隔5mm-10mm,通常范围为耻骨联合下缘至髂前上棘,肿块巨大者上界应完全覆盖病灶。扫描前夜起分次口服1％-2％泛影葡胺水溶液,总量约1500ml,以充分充盈盆腔肠管,已婚妇女扫描前常规使用阴道塞。本组病例均经手术病理证实。结果在96例患者中共检出108个病灶,手术病理报告畸胎瘤22例(22个病灶),囊腺瘤14例(14个病灶),卵巢囊肿20例(24个病灶),囊腺癌32例(36个病灶),转移癌4例(8个病灶),其它病变4例(4个病灶)。结论 CT发现病变的敏感性100％,定性诊断准确率87％。

Purpose To summarize the CT appearances and the diagnostic value of ovary masses. Methods Ninety-six patients of ovary masses confirmed by surgical pathology were retrospectively analyzed with age from 15-80 years old（mean 47 yrs）. After the intestinal preparation with 1%-2% contrast material of 1500ml, CT examination was respectively performed including the plain scanning and the enhanced scanning with non-ion contrast injection though the elbow veins. Results There were 108 lesions in the 96 patients. The patients were classified into the teratoma（n=22 cases）, cystadenoma（n=14 cases）, cystcarcinona（n=32 cases）, metastasis（n=4 cases）,cyst（n=20 cases ） and the other （n=4 cases）. Conclusion The diagnostic sensitivity and the accurate rate of ovary, masses by CT respectively are 100 per cent and 87 per cent in the group.
