Interstitial lattice shadow and mediastinal lymphadenopathy with an elevation of carcinoembryonic antigen in severe pulmonary alveolar proteinosis.
A case of severe pulmonary alveolar proteinosis (PAP) with interstitial involvement, mediastinal lymphadenopathy and an elevation of carcinoembryonic antigen (CEA) in the bronchoalveolar lavage (BAL) fluid and the serum is presented. Alveolar macrophages may play a major role in these rare and seemingly unrelated findings.
