  • Abstract
  • Look Inside

A 30-year-old man began to experience palpita-tion, chest pain and fever 3 weeks prior to admission. An electrocardiogram showed evidence suggestive of left atrial overloading, and frequent atrial premature beats. A chest roentgenogram revealed an abnormal shadow behind the right upper portion of the heart. A cross-sectional echocardiogram demonstrated abnormal echoes with ill-defined margins in the left atrium and a picture of Computed Tomography (CT) was thought to show a left atrial tumor. How-ever left atriography suggested it to be an extra-cardiac tumor which was compressing the left atrium. Therefore, reconstruction CT was perform-ed and with the use of high CT numbers, the cyst was considered to be subcarinal in position. The CT also showed a calcified mass which was mobile within the cyst.

At thoracotomy, an 6×3 cm cyst was removed completely and a diagnosis of bronchogenic cyst was established histopathologically.

In this report, ECG abnormalities suggestive of left atrial damage and the diagnostic usefulness of reconstruction CT are stressed.
