From: Cross-sectional imaging of acute gynaecologic disorders: CT and MRI findings with differential diagnosis—part I: corpus luteum and haemorrhagic ovarian cysts, genital causes of haemoperitoneum and adnexal torsion

Fig. 18

Two surgically proven cases of adnexal torsion. a, b Axial (a) and coronal (b) CT images show enlarged left ovary (arrowheads) with thickened oedematous periphery (thin arrows), containing a mixed-attenuation roundish mass with fat-attenuation foci and a calcification, corresponding to a mature cystic teratoma. Note the ipsilateral attraction of uterus (+), minimal fluid in the peritoneal cul-de sac (asterisk in a). c–f Unenhanced (a) and post-contrast (d–f) CT images show large midline pelvic mass (arrowheads) consistent with malignant teratoma with poor, irregular enhancement that displaces the uterus and bladder. Note the peritoneal effusion (asterisk) and congested ovarian vessels on the right side
