摘要
目的 提高胃肠道肿瘤卵巢转移的诊断正确率。方法 回顾性分析 2 1例胃肠道肿瘤卵巢转移的CT表现。年龄 2 6～ 6 1岁 ,中位年龄 41岁。原发为胃肿瘤 6例 ,结直肠肿瘤 15例。结果 2 1例患者CT共检出卵巢病灶36个 ,实性或以实性为主的病灶 32个 ,实性成分表现以较大团块为主 ,占 86 .1% (31/ 36 )。强化后密度不均 ,表现为 :①厚壁及分隔的强化较实性团块明显 4个 ;②强化肿物内裂隙状低密度 6个 ;③分隔条索状强化 4个 ;④肿物周边强化 2个 ;⑤肿物内囊壁明显强化 2个。结论 胃肠道肿瘤卵巢转移常表现为实性或以实性为主的病变 ,增强后强化明显不均 ,与病变的组织结构有关。
Objective To improve the diagnostic accuracy of ovarian metastases of gastrointestinal tumors with CT scans. Methods CT findings of 21 patients (age range 26-61 years) with ovarian metastases of gastrointestinal tumors were reviewed. Primary neoplasms were located in the stomach (6 cases), colon (12 cases) and rectum (3 cases). Results Of 21 cases, CT found 36 ovarian lesions and eight ninths were solid or predominantly solid lesions. The solid parts were almost big masses(31/36), and had asymmetric attenuation after contrast enhancement. There were four types of enhancement:①Enhancement of thick cystic walls and septa were more distinct than solid masses (4 lesions). ②Cleft like low density in the enhanced tumors (6 lesions). ③Thin enhancement like septa (4 lesions). ④Peripheral enhancement (2 lesions). ⑤Apparently strong contrast enhancement of the wall of the intratumoral cysts (2 lesions). Conclusion Ovarian metastases of gastrointestinal tumors are always solid or predominantly solid. They are distinctly asymmetric after contrast enhancement, which relate to their histological structure.
