A 78-year-old man with newly diagnosed treatment-naïve chronic lymphocytic leukaemia (CLL) was referred to a pulmonary clinic for 1 month of dry cough and dyspnoea on exertion. Further workup with CT of the chest showed patchy ground-glass opacities predominantly on the right side. The patient was started on empiric antibiotic for presumed community-acquired pneumonia but did not have any improvement in his symptoms and eventually required supplemental oxygen. Bronchoscopy with bronchoalveolar lavage from the right middle lobe showed Pneumocystis jirovecii cysts on Grocott methenamine silver stains. The patient was HIV negative. He was placed on P. jirovecii pneumonia (PJP) treatment with clindamycin and primaquine due to history of significant allergy to sulfa drugs. The patient’s symptoms completely resolved after a 21-day course of treatment and no longer needed supplemental oxygen. This case highlights the importance of keeping PJP infection in differential diagnosis in both treated and untreated patients with CLL with dyspnoea and pulmonary infiltrates.
