Chorioangiomas are common placental neoplasms that are primarily asymptomatic, but the larger subtypes have a variable presentation and can result in severe pregnancy complications. We report a case of a pregnant patient who presented with a 10 x 12 x 10 cm placental chorioangioma at 32 weeks, despite an unremarkable ultrasound at 28 weeks. Since these more substantial chorioangiomas can induce fetal mortality, close surveillance with perinatology and neonatology consultation is necessary to enhance the probability of a favorable patient prognosis.
