A 59-year-old woman was referred to our institution with atrial flutter and pre-syncope. A chest roentgenogram and an echocardiogram were obtained and showed a large intrathoracic mass (A and B, arrow). Cardiac magnetic resonance with steady-state free precession sequences, T2-weighted images, and inversion-recovery images, as well as 3-dimensional whole-heart acquisition was performed for further characterization of the lesion. The diagnosis of a pericardial cyst (arrows in C, D, and E)was made, and was confirmed at surgery as well as histologically (C to F). Post-operatively, the patient was in sinus rhythm again.
Pericardial cysts are rare benign intrathoracic lesions with a prevalence of 1:100.000 (1). For asymptomatic patients, conservative management with short follow-up periods is recommended. However, for symptomatic patients or for patients suffering from complications, surgery should be considered (2).
