AJR Teaching File: Right Atrial Mass in a Woman with Uterine Fibroids

Abstract

A 48-year-old woman with a history of hypertension who had undergone dilatation and curettage for vaginal bleeding related to uterine fibroids presents with palpitations and chest pain. A heart murmur is detected on physical examination. Echocardiography performed elsewhere depicted a possible right atrial myxoma with inferior vena caval involvement. She was then referred to our institution for further evaluation and treatment.

Right Atrium Myxoma After Lung Adenocarcinoma

“…In a patient with a history of lung adenocarcinoma, who has right heart failure symptoms, cardiac metastasis from the lung will be on top of the differential diagnosis list ( 1 , 3 ). Where benign right heart tumor and myxomas are already rare ( 4 - 9 ), a right atrium myxoma in a patient with a history of lung cancer, uterine myoma and breast fibroadenoma has been limited to only a few case reports ( 10 ). This may suggest a genomic affinity or similarity; if so, those with multiple different type soft tissue masses should be screened for a heart mass before the mass becomes complicated.…”
