Abstract Objective: To explore the CT imaging features of sclerosing stromal tumors(SST) of ovary, in order to improve diagnosis. Methods: CT manifestations of 12 cases with SST of ovary confirmed by pathology were analyzed retrospectively. Results: Among the 12 cases with SST of ovary, 7 of them located in the left ovary and 5 cases right. The tumors size varied from 3.6～12.1 cm in the largest diameter. Unenhanced CT scans showed mixed density mass with cystic and solid density, 10 cases(83%) were predominantly solid-density tumors, and 2 cases(17%) predominantly cystic-density tumor. Calcifications were seen in 4 cases(33%). Contrast-enhanced CT scans showed heterogeneous enhancement significantly in all cases. The features were as follows: According to the range of enhancement: 12 cases(100%) solid components appeared as progressive enhancement, similar to “hepatic cavernous hemangioma”, but the cystic components has no enhancement in the whole course. According to the mode of enhancement: ①Early-fast sustained enhancement: the curve of enhancement of the solid components in 7 cases(58%) appeared as peak-shape, but the cystic components has no enhancement in the whole course. Two cases showed dilated tortuous arteries enhanced obviously around the mass in the arterial phase. ②Gradual increase enhancement:In 5 cases(42%) the curve of enhancement of the solid components appeared as straight line shape, but the cystic components has no enhancement in the whole course. Two cases showed a multiloculated cystic mass with irregularly thickened septae and tumor wall. Conclusion: SST of ovary has some specific CT manifestations, CT examination combined with clinical manifestations is helpful for the diagnosis of SST of ovary.
