Cryptococcal Pneumonia in a Patient with Sickle Cell Disease

We present the findings in a patient having sickle cell disease who developed multilobar pneumonia. Cultures of bronchial aspirates and histologic specimens grew Cryptococcus neoformans. There was neither spontaneous clearing of the infection nor a response to bactericidal antibiotics. The patient had no underlying malignant neoplasm or immunodeficiency as indicated by history, physical examination, and specialized tests of humoral and cell-mediated immunity.
