BackgroundLithopedion is a word derived from the Greek words lithos, meaning stone, and paidion, meaning child, to describe a fetus that has become stony or petrified. Lithopedion is a rare complication of pregnancy which occurs when a fetus dies and becomes too large to be reabsorbed by the body. This entity in rare circumstances can be challenging for physicians to diagnose since it has a range of clinical manifestations.Case presentationWe present a case of a 55-year-old, gravida IV para III, Ethiopian woman from Ethiopia with a retained fetus and vesicovaginal fistula after an obstructed labor and a neglected intrauterine fetal demise of approximately 22 years. The diagnosis was confirmed by suggestive clinical history, physical examination findings, and an abdominopelvic computed tomography scan. Laparotomy and removal of the lithopedion was done and our patient was sent to a fistula hospital for vesicovaginal fistula repair.ConclusionThis case is a rare phenomenon in which the dead fetus remained in the uterus for a long time after a neglected obstructed labor and uterine rupture.
