Extensive pulmonary cryptococcosis as a presentation in an immunocompetent young male: A fluorodeoxyglucose positron emission tomography/computed tomography finding.

A 42-year-old male presented with a dry cough, breathlessness, and fever. He underwent a computed tomography that revealed large consolidation in the right lung. Biopsy revealed Cryptococcus neoformans. He was on antifungal for 4 months with no clinicoradiological improvement. ¹⁸F- fluorodeoxyglucose positron emission tomography/computed tomography (¹⁸F-FDG PET/CT) showed consolidations in the right lung with multiple lung nodules. ¹⁸F-FDG PET/CT ascertains the diagnosis of residual fungal infection and rules out extrapulmonary involvement.
