Incarceration of a gravid uterus with massive placental enlargement and fetal triploidy at 19 weeks of gestation – A case report on the simultaneous presence of two rare conditions

Abstract

This article reports a rare case of uterine incarceration in pregnancy concurrent with nonmolar fetal triploidy and massive placental enlargement in a 35-year-old primigravida. The patient presented with abdominal discomfort and peripheral edema at 19 weeks of gestation.Diagnostic assessments revealed a retroflexed uterus with a massively enlarged placenta and a severely growth-restricted fetus. Uterine repositioning was successfully achieved after rectal filling. However, spontaneous fetal demise led to vaginal delivery. The fetal autopsy confirmed female triploidy. Histopathology of the placenta showed no features of a partial mole.This case highlights the challenges in diagnosing uterine incarceration in pregnancy, the need for early intervention and the complexity of managing multiple concurrent pathologies.
