AJR Teaching File: Right Atrial Mass in a Woman with Dyspnea on Exertion

Benjamin J. Holloway, and Prachi P. Agarwal

Case History
A 50-year-old woman presents with nonspecific chest pain, a syncopal episode, and increasing dyspnea on exer­tion without edema, orthopnea, or paroxysmal nocturnal dyspnea. CT pulmonary angiography is performed to evalu­ate for pulmonary embolism. This is followed by cardiac MRI to further evaluate abnormal cardiac findings identi­fied on CT pulmonary angiography. CT of the abdomen that was performed 7 months previously to investigate up­per abdominal pain is also reviewed and found to include the area of abnormality.
