Abstract
|
|
|
Forty two cases of middle lobe syndrome who had been hospitalized between 1980
and 1987 were reviewed by clinical, radiological, bacteriological, histopathologic and
bronchoscopic presentation. In our study, tuberculosis (45%) was the main cause and the
remaining were pneumonia (24%), bronchiectasis (19%) and malignant tumor (7%). The
chief complaints of the patients in order were coughing, chest discomfort, dyspnea and
hemoptysis. By bronchoscopic examination, 55% of the cases demonstrated well
preserved bronchial lumens, which strongly suggest that impairment of collateral
ventilation is the main pathological change of middle lobe syndrome.
The remaining 45% showed narrowing or complete obstruction of right middle lobe
bronchus. The follow up study showed more favorable prognosis in pneumonia and
bronchiectasis than tuberculosis or malignancy.
