Case 1 with SBT-MP. 27-year-old woman with right ovarian SBT-MP. Axial T2WI (a) shows a multicystic mass on the right side of the uterus (U) with intracystic mural nodules showing inhomogeneous slight hyperintensity (arrows). Hypointense internal branching architecture is not detected. A small amount of ascites is noted (arrowhead). The mass shows homogeneous hypointensity on axial T1WI (b). The mural nodules are homogeneously enhanced after administration of gadolinium DTPA (c) and hyperintense on DWI (d). The corresponding histopathological section shows papillary architecture with a hierarchical internal branching fibrous stalk, with diffuse proliferation of tumor cells in elongated micropapillary projections with little or no stromal support peripherally (arrows). Whereas the co-existing typical SBT has a peripheral edematous stalk with superficial epithelial cells, a loose structure of papillary projections is noted in the same papillary projection (arrowheads) (e)
