[Application of CT scan in diagnosis of pathological type and origin of metastatic ovarian tumors].

ABSTRACT

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.
