A 27-year-old woman presenting at the emergency department with acute pelvic pain. Abdominal US (a) shows a rounded lesion adjacent to the uterus, clearly separate from the left ovary. Axial CT scan shows a voluminous mass in the pelvic cavity (b); for the characterisation an MRI was required. Axial (c) and coronal (d) T2-weighted and T1-weighted images (e) of the pelvis show a right heterogeneous adnexal mass (arrow) with fallopian tube haematoma. Note the normal ovary (short arrow) in (c). Pre-contrast T1-weighted fat-saturated image (f) shows bloody ascites (short arrows). These findings are due to ectopic pregnancy with tubal rupture and haemoperitoneum
