Tubal ectopic pregnancy in a 44-year-old woman with acute abdominal pain and positive results of a pregnancy test (elevated β-hCG level). (a) Coronal and (b) axial T2-weighted images show a predominantly hypointense saclike cystic adnexal mass (white arrows) in the left side of the pelvic cul-de-sac. (c) Axial and (d) coronal fat-suppressed T1-weighted images show a distended fallopian tube with low to intermediate signal intensity content and high signal intensity thick wall (white arrows), a finding consistent with hematosalpinx. (e) Axial DW image (b = 800 s/mm²) demonstrates increased signal of the lesion (white arrow). Note the lack of an intrauterine pregnancy. (f) Histologically, villi in the tubal wall confirmed the diagnosis of ectopic tubal pregnancy (H&E 200X)
