Review Case Reports[Mediastinal esophago-bronchogenic cyst presenting as a single mass].
An abnormal shadow was found on a chest X-ray film of a 42-year-old man. The mass was 17 x 12 x 11 cm, smooth, round, homogeneous, and was seen in the left upper lung field. Chest computed tomography revealed a cystic mass in contact with the left lung, the chest wall, the esophagus, and the aorta. ⋯ The final diagnosis was mediastinal esophago-bronchogenic cyst. In previously reported cases, two cystic masses were connected by a canal. The findings in this case support the theory by Yoshii that this type of cyst originates from the diverticulum of the foregut near the lung bud.

[Prediction of outcome after acute exacerbation of idiopathic interstitial pneumonia].
Some patients with chronic idiopathic interstitial pneumonia (IIP) experience acute exacerbations (AE). Because the precise mechanisms of AE in patients with IIP remain unclear, the treatment for AE is not established and the efficacy of steroids is controversial. Consequently, it is difficult to predict outcomes in patients with AE of IIP. ⋯ Of the 22 non-survivors, 7 had received medication before the AE; none of the survivors had received medication before the AE. At the time of the AE all patients were treated with steroid pulse therapy, and the dose of methylprednisolone used, did not differ significantly between groups. These data suggest that three factors are closely related to responsiveness to steroid therapy and to clinical outcomes after AE in patients with IIP: 1) age at the onset on IIP, 2) respiratory status before the AE, and 3) disease activity as reflected by inflammatory reactions.
