18-year-old female with ovarian torsion. Color Doppler-Ultrasound image shows a large cystic lesion (thin arrow) in the right adnexa with thick internal septations and mural nodules. Vascular flow was noted within the thick septa (thick arrow).

Ultrasound with color Doppler showed a large, predominantly cystic, right adnexal lesion with thin septations, mural-septal nodules, and intralesional mural-septal vascularity (Fig. 1).
18-year-old female with ovarian torsion. Contrast-enhanced CT axial image shows thickened right adnexa (thick arrow) interposed between the cystic lesion (thin arrow) and uterus (Ut) which raised suspicion of adnexal torsion. Mild rightward deviation of uterus is also noted.

Contrast-enhanced CT showed a thickened right ovary interposed between the cystic lesion and uterus, which raised suspicion of ovarian torsion (Fig. 2).
18-year-old female with ovarian torsion. Fat-suppressed, T2-weighted axial MR image showing hyperintense signal within the lesion (thin arrow) with papillary projections (thick arrow). Uterus (Ut) and left ovary (LO) are also noted with mild free fluid in the pouch of Douglas (arrowhead).

MRI, which also showed intralesional papillary projections (Fig. 3A). MRI clinched the diagnosis of torsion with precise demonstration of a "whirlpool" appearance of the right adnexa (Fig. 3B). More than two twists of vascular pedicle were precisely demonstrated on MRI, which corroborated the intra-operative findings.
