A clinical vignette highlighting the differential diagnosis of a left atrial mass discovered on echocardiography in a patient with a history of malignancy.
Echocardiographic thread-like left atrial masses in breast cancer warrant broad differential and multimodality imaging; leaves open definitive etiology without histopathology.
A 54-year-old female with medical history significant for breast cancer status post right lumpectomy, chemotherapy, and radiation currently in remission, presented with a complaint of progressive dyspnea with exertion over a four-month timeframe.Transthoracic echocardiography (TTE) revealed a left atrial mass raising suspicion of metastasis.The mass was somewhat tubular and thread-like in appearance.
