Incarceration of the uterus in pregnancy

Uterine incarceration is a rare complication of pregnancy, usually presenting between 12 and 20 weeksʹ gestation, when the gravid uterus normally ascends through the pelvic brim. Conditions such as pelvic inflammatory disease, endometriosis, postoperative adhesions, posterior wall leiomyomas, and pelvic contraction may lead to fixed retroflexion of the uterus, predisposing to this condition. A case of incarceration is presented. Clinical features, diagnosis, treatment, and potential complications are discussed.
