title: Cavitary pulmonary infection with Mycobacterium avium observed by bronchoscopy.
abstract: A 58-year-old man was admitted to our hospital because of fever and loss of appetite. He had undergone surgery for esophageal cancer. A chest radiography 12 years after the surgery revealed cavitary lesions in the right upper lobe of the lung. The patient was then diagnosed as having Mycobacterium avium infection. The cavitary lesions worsened 2 years after clarithromycin monotherapy. Bronchoscopy was performed to observe the interior of the cavity. Gray debris adhering to the cavitary wall decreased after intensive treatment with Streptomycin, rifabutin, levofloxacin, and ethambutol. This is a rare case in which treatment efficacy of M. avium infection was directly observed by serial bronchoscopy.
