Disappearance of the blood supply to a giant uterine myoma due to childbirth: A CARE-compliant article

RATIONALE: Giant uterine myomas may be life-threatening due to pressure effects on the lungs and other contiguous organs. PATIENT CONCERNS: A 32-year-old pregnant Asian woman was admitted to our hospital early in her pregnancy with a pre-pregnancy history of multiple uterine myomas. DIAGNOSIS: She was diagnosed with multiple giant uterine myomas in pregnancy. INTERVENTIONS: No intervention was performed on the woman. OUTCOMES: A reduction in tumor size and disappearance of tumor blood supply were seen on conventional and contrast-enhanced ultrasounds (CEUS) on postpartum day 34. Mass volume gradually decreased and no blood flow signals were seen on CEUS during postpartum follow-up. LESSONS: Childbirth can block the blood supply of giant uterine myomas and reduce mass size. In such cases, childbirth may be considered therapeutic.
