Objective: To evaluate the application of CT scan in diagnosis of pathological types and origins of metastatic ovarian tumors.
Methods: Clinical data, histopathological results and CT images of 43 patients with pathologically-proved metastatic ovarian tumor were retrospectively analyzed. Diagnostic values of CT imaging for pathological type and origin of metastatic ovarian tumors were evaluated.
Results: The pathological types of metastatic ovarian tumor were related to the size of the lesion (P<0.01), while not related to the sites of lesion (unilateral or bilateral), the cystic-solid and mixed lesions with or without separation (all P>0.05). Metastatic ovarian tumors of colorectal origin were usually unilateral lesions, and showed cystic or cystic-solid masses, while those of gastric origin were usually bilateral lesions, and showed solid or solid-based masses.
Conclusions: CT imaging may be of value in diagnosis of pathological types and origin of metastatic ovarian tumor.
目的: 探讨CT表现与胃及结直肠来源卵巢转移性肿瘤病理类型和肿瘤来源之间的相关性，分析并评估其诊断价值。
方法: 对经病理学检查证实的43例胃和结直肠来源的卵巢转移性肿瘤患者的临床资料、病理学检查结果和CT影像学资料进行回顾性分析，评估CT表现对卵巢转移性肿瘤的病理类型和肿瘤来源的诊断价值。
结果: 卵巢转移性肿瘤的病理类型与转移灶大小相关（ P < 0.01），而与转移灶部位（单双侧）、囊实性和囊性及混合性转移灶有无分隔无关（均 P > 0.05）。对照两种不同组织来源转移瘤的CT表现，其中结直肠来源的转移灶多为单侧发病，病变多为囊性或以囊性为主的囊实性；胃来源的转移灶多为双侧发病，且病变多为实性或以实性为主的囊实性。
结论: CT表现对卵巢转移性肿瘤的病理类型和转移灶来源的判断有一定的参考价值。
