title: Thickening of the posterior wall of the bronchus intermedius in right lung pneumonia.
abstract: A recent paper in the literature described thickening of the posterior wall of the bronchus intermedius (PWBI) in patients with congestive heart failure, and/or enlarged lymph nodes and neoplastic infiltrations. At this institution we have seen two recent cases of right upper lobe viral pneumonia demonstrating abnormal thickening of the posterior wall of the bronchus intermedius on lateral chest radiographs. A retrospective survey of our museum cases supported the hypothesis that pneumonia of the right lung, involving the right upper, middle, lower or any combination of these lobes may show thickening of the posterior wall of the bronchus intermedius.
