ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the application of CT scan in diagnosis of pathological types and origins of metastatic ovarian tumors.</p><p><b>METHODS</b>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.</p><p><b>RESULTS</b>The pathological types of metastatic ovarian tumor were related to the size of the lesion (<0.01), while not related to the sites of lesion (unilateral or bilateral), the cystic-solid and mixed lesions with or without separation (all>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.</p><p><b>CONCLUSIONS</b>CT imaging may be of value in diagnosis of pathological types and origin of metastatic ovarian tumor.</p>
