[Clinical analysis of 6 cases of pericardial cysts]

We present a clinical analysis of 6 cases of pericardial cysts. There were two males and four females. Only one case of them had complaint of persistent cough. Four of 6 were observed in right costo-phrenic angle, and 2 were in left costo-phrenic angle. Surgical excision was performed in 6 cases, and all patients recovered good health. We suggest that in cases of pericardial cysts, surgical treatment should be performed, even if patients would not have remarkable complaint.
