Abstract:
A 79-year-old female who had been observed for an intrapericardial cyst for 3 years was admitted due to severe dyspnea and back pain. During 3 years observation, there were no symptoms and no growth of the cyst. Computed tomography scans showed rapid expansion of the cyst compared with an magnetic resonance imaging (MRI) taken 9-days before when she visited our hospital for the 1st time. Urgent complete extirpation of the tumor was successfully done and a histological diagnosis found it was an intrapericardial bronchogenic cyst. This is a 1st report of intrapericardial bronchogenic cyst of which rapid expansion is clearly demonstrated by radiology. It is suggested that complete surgical excision of intrapericardial bronchogenic cysts at the time of diagnosis even if asymptomatic.
