We encountered nine patients with acquired immunodeficiency syndrome (AIDS). All were men, and ranged in age from 25 to 63 (mean,43.1±13.5years).One patient was a Thailander,one was a Brazilian and the others were Japanese. All patients presented CD4＋T-lymphocyte counts under 100/μl. Eight patients were admitted to our hopital because of pneumocystis carinii pneumonia (PCP), and the other was admitted with toxoplasmosis.Chest X ray films and chest computed tomography(CT)scans of the patients with PCP revealed distinct radiographic findings. We must be aware of the possibility of PCP and human immunodeficiency virus (HIV) infection when we encounter patients with atypical radiographic findings of interstitial pneumonitis.Article信州医学雑誌 48(2): 97-103(2000)journal articl
