Case 7 with typical SBT. 65-year-old woman with left ovarian typical SBT. Axial T2WI (a) shows a left ovarian cystic mass with intracystic mural nodules. The largest papillary nodule (arrows) demonstrates inhomogeneous slight hyperintensity with internal hypointense foci. On T1WI (b), the SI of the cystic content shows slight hyperintensity. After administration of gadolinium DTPA (c), the mural nodules are enhanced weakly. On DWI (d), the largest mural nodule shows hypointensity equal to the SI of muscle. A photomicrograph of the area corresponding to the largest papillary nodule (e) shows a bluntly branched fibrous stalk without edema and hyaline degeneration. More spaces between papillae are found due to the lack of densely branched papillae peripherally (arrows), leading to hypointensity on DWI
