Incarcerated gravid uterus: A rare but potentially devastating obstetric complication.

Incarceration of the gravid uterus is a rare obstetric complication characterized by entrapment of the gravid uterus between the sacral promontory and pubic symphysis. Clinical symptoms are highly variable and may include low back pain, urinary retention, and nausea. A presumptive diagnosis can often be established based on correlation of clinical history and physical examination. However, ultrasound and/or pelvic magnetic resonance imaging are essential for confirmation. Herein, we describe a 30-year-old female who presented with uterine incarceration and discuss the diagnosis, imaging features, and management of this uncommon but important clinical entity.
