(a) Axial T2 weighted imaging (TR/TE, 6130/100 ms) showed an intrauterine mass (arrow) with clearly defined inhomogeneous high intensity. (b) The mass (arrow) showed inhomogeneous contrast enhancement with cystic changes of variable sizes on post-contrast fat-suppressed T1 weighted imaging (TR/TE, 575/13 ms), high signal intensity on diffusion-weighted imaging (DWI) (b = 1000 s/mm2, TR/TE, 4317/70 ms) (c) and low signal intensity (0.88 × 10−3 mm2/s) on apparent diffusion coefficient (ADC) maps (d). A 22-mm solid nodule accompanied by a tiny cyst was detected in the right ovary (a–d arrowhead). The nodule showed homogenous iso signal intensity with the uterine tumor on T2WI (a). It showed homogeneous contrast enhancement with a tiny cystic change (b), marked high signal intensity on DWI (c) and low signal intensity (0.66 × 10−3 mm2/s) on ADC maps (d). Whole-body 18F-FDG positron emission tomography-computed tomography (PET-CT) showed increased FDG uptake (maximum standardized uptake value: 8.2) in the uterine tumor (arrow) and no abnormal FDG uptake in any other organs, including the right ovarian nodule (e arrowhead)
