Key CT differential diagnoses of haemorrhagic ovarian cysts. a, b Unenhanced (a) and postcontrast (b) CT images of bilateral endometriomas (arrowheads) occupying the rectouterine pouch in a ‘kissing ovaries’ configuration. Note the mildly inhomogeneous attenuation and septation (thin arrow in b). c, d Ovarian carcinoma in a premenopausal woman with predominantly cystic pattern, septations (thin arrow in d) and a solid, enhancing eccentric mural vegetation (asterisk in c). e, f Unenhanced (e) and post-contrast (f) images of a postoperative collection (complex serocele, arrowheads) involving the adnexal region, showing septations (thin arrows). Note the right ureteral stent and suture at the sigmoid colon after multiple surgeries for Crohn’s disease
