ct

The right ovary appears markedly enlarged measures about 7 x 7 cm, centrally located (midline in position) in the pelvis, with multiple peripherally displaced follicles and hyperdense central stroma, associated with twisted vascular pedicle (whirlpool sign) and pelvic free fluid.

Case Discussion

The most common risk factor for ovarian torsion is mature cystic teratoma

The primary imaging modality for ovarian torsion evaluation is ultrasonography (US). 

The function of computed tomography (CT) has grown, and it is now being utilized more frequently in the diagnosis of abdominal pain.

Common CT features of ovarian torsion include: enlarged ovary, midline position, multiple peripherally displaced follicles, hyper-dense central stroma, twisted vascular pedicle and pelvic free fluid 1. As in this case most of these findings are seen, urgent surgery confirmed the diagnosis.
