- 11.A 41-year-old man with a 6 kg weight loss over the past 3 months now has had worsening fever, non-productive cough, and dyspnea for the past 3 days. His temperature is 38.2 C and there are diffuse rales in both lungs on auscultation. A chest radiograph shows patchy infiltrates in both lungs. Laboratory studies show a WBC count of 3250/microliter with differential of 78 segs, 3 bands, 5 lymphs, 11 monos, 2 eosinophils, and 1 basophil, Hgb 13.8 g/dL, Hct 41.4%, MCV 91 fL, and platelet count 317,000/microliter. His CD4 lymphocyte count is 79/microliter. Cryptosporidium parvum organisms are found in a stool specimen. A bronchoalveolar lavage is performed, yielding fluid that microscopically demonstrates pink, foamy exudate with little inflammation. Which of the following additional findings on microscopic examination is he most likely to have in the BAL specimen?
- A.
Acid fast bacilli
- B.
Branching septate hyphae
