A 62-year-old married female patient, complaining of abdominal pain and distention, and nausea. a Transabdominal ultrasound reveals right adnexal well-defined anechoic Complex cystic lesion measuring about 11 × 9 cm with thick nodular internal septations b Transabdominal ultrasound shows moderate flow on color Doppler. c Axial T1-weighted image reveals right ovarian well-defined bilocular cystic lesion measuring about 12 × 10 cm with mural nodules, inseparable from the sigmoid colon and uterus. The lesion displays low signal in T1WI small mural nodules displaying low signal intensity d Axial T2-weighted image shows intermediate signal intensity of the mural nodules e Axial T1 post contrast shows mild post contrast enhancement of the lesion. f Diffusion-weighted image shows restricted diffusion of the mural nodule (g) DCE-MRI, dynamic contrast-enhanced MRI Curve type 3: Initial rise steeper than that of myometrium. Scoring: O-RADS US 4, CS 2, and O-RADS MRI 5, the lesion was diagnosed as right ovarian mucinous cystadenocarcinoma by histopathology
