A 50-Year-Old Woman With Uterine Myomatosis, Rapidly Progressive Dyspnea, and Lower Extremity Edema.

CASE PRESENTATION: A 50-year-old woman with morbid obesity (BMI, 49 kg/m2) was admitted to the ED due to shortness of breath triggered by mild to moderate efforts over the previous 3 weeks that rapidly progressed to dyspnea at rest and became associated with oppressive chest pain and edema of the lower extremities. Four months prior to admission, she had been diagnosed with a uterine mass (18 × 21 cm2) suggestive of a leiomyoma, manifesting with abnormal vaginal bleeding and microcytic hypochromic anemia (Fig 1).
