External compression from a large bronchogenic cyst caused an abnormal left atrial membranous structure on transthoracic echocardiography in a 44-year-old woman with dyspnea.
A large bronchogenic cyst can cause external compression mimicking an abnormal left atrial membranous structure on transthoracic echocardiography.
Consider extrinsic compression in unexplained LA membrane-like structures on echocardiography; extends differential diagnosis in symptomatic patients.
A 44 year old woman was referred for echocardiographic examination because of recent onset of dyspnoea. She had been diagnosed with bronchial asthma by a private clinic. On physical examination, however, pulmonary auscultation revealed bilateral vesicular breath sounds without rales and good heart sounds without murmur. Transthoracic …
