(A) PET/CT showing enlarged, FDG-avid mediastinal lymphadenopathy. (B) Hematoxylin-eosin and (C) mucicarmine stains of an endobronchial ultrasound-guided fine-needle aspirate from the mediastinal lymph node showing many encapsulated yeast forms with narrow-based budding, morphologically consistent with Cryptococcus species.

Positron emission tomography/CT (PET/CT) performed to evaluate for lymphoma progression showed enlarged, fluoro-2-deoxy-D-glucose (FDG)-avid mediastinal lymphadenopathy, which was new compared to 3 months prior, and had a maximum standardized uptake value (SUV) of 7, suggestive of active lymphoma (Fig. 1A). Hematoxylin-eosin (Fig. 1B) and mucicarmine (Fig. 1C) stains of an endobronchial ultrasound-guided fine-needle aspirate from the lymph node revealed many encapsulated yeast forms with narrow-based budding, morphologically consistent with Cryptococcus species, and no malignant cells.
