Bronchogenic carcinoma in HIV-positive patients: findings on chest radiographs and CT scans.

Abstract

Bronchogenic carcinoma usually manifests as a peripheral upper lobe mass in HIV-positive patients with a history of tuberculosis or Pneumocystis carinii pneumonia, whereas central masses are more common in patients without a history of thoracic opportunistic infection. Carcinoma should be suspected in patients with peripheral lesions that persist despite appropriate antibiotic therapy.
