C Reactive protein, 20 mg/ L (normal value <6 mg/ L).An abdominal ultrasound revealed a multilocular cystic mass of the left ovary that measured 90 x 80mm (Fig. 1).
Axial CT: heterogeneous left ovarian mass (arrow) with fat (discontinued arrow), calcifications (angled arrow) associated to fat stranding (star). Note the cystic mass of the right ovary (curved arrows).

A unilocular cyst of the right ovary, measured 80 x 50 mm, was also noted (Fig. 2).
Pelvic MRI: axial T2W (a,b,c) and coronal T2W (d), T1W (e-f) and T1 with fat saturation and gado: left sided mass with fat areas (blue arrow) and calcification (angled arrow) associated to diffuse fat stranding with intense enhancement (red star) and multiple collections (orange star). Note the cystic mass of the right ovary, classified O-RADS 2(curved yellow arrows).
