A Symptomatic Calcified Pericardial Cyst

We describe a 59-year-old man with a large calcified pericardial cyst who presented with recurrent spells of presyncope and dyspnea. Presyncope occurred on several occasions and was confined to when the patient was walking. Dyspnea occurred in the supine and semirecumbent positions and unpredictably during walking, especially when in a hot or humid environment. The patient ’s medical history was notable only for Lyme disease that had occurred the previous year.
