ABSTRACT
<p><b>OBJECTIVE</b>In order to improve the preoperative diagnostic accuracy, the computed tomographic (CT) features of ovarian Brenner tumor were described and analyzed.</p><p><b>METHODS</b>CT image and clinical data of nine patients with pathologically confirmed Brenner tumor were collected and analyzed retrospectively. There were 8 benign lesions and 1 borderline lesion.</p><p><b>RESULTS</b>All lesions in the nine cases were unilateral, round, lobulated or irregular in shape and well defined, in a mean diameter of 7.8 cm. Among the nine cases, 5 were benign tumors with uniform structure, 3 were benign tumors accompanied with other pathological components, and 1 was borderline tumor. On the CT images, the 5 uniform benign lesions showed to be solid tumor of low density (lower than that of muscle) or with small cyst inside, two of the 5 lesions had calcification, and other 2 lesions showed slightly heterogeneous enhancement after enhanced scanning. The 3 benign Brenner tumors accompanied with other pathological structures were solid-cystic or cystic, with a clear demarcation of solid and cystic components. The density of solid parts was lower than that of muscle, and slight enhancement, and one of them had calcification. The one borderline tumor was a heterogeneous solid one and its density was higher than that of muscle, with a large proportion of low density and large calcification, and moderately enhanced after enhancing. None of the 9 cases had metastasis or effusion.</p><p><b>CONCLUSION</b>Ovarian Brenner tumors are usually unilateral and often accompanied with other type of tumor components. When a tumor is of uniform component, the CT imaging often shows a homogeneous solid tumor with homogeneous or heterogeneous density. When a tumor is accompanied with other tumor components, it may be solid-cystic or cystic and has partial calcification. After enhancing, a benign Brenner tumor is slightly enhanced, while the borderline one is moderately/highly enhanced.</p>
