We report a case of Talaromyces marneffei fungemia in a patient with HIV infection with a history of travelling to southern China. At first, Pneumocystis pneumonia was considered in this case because chest CT images showed typical ground-glass opacity and elevated β-D-glucan levels. However, PCR testing of sputum for Pneumocystis jirovecii was negative and a filamentous fungus was isolated from blood cultures. The cultured fungus was subsequently identified as T. marneffei, and the patient was considered to have pneumonia caused by this organism. However, skin disease and lymphadenopathy, which are common in T. marneffei infections, were not observed during the disease course. This patient was successfully treated with voriconazole and consequently the chest CT shadow disappeared. In the present case, T. marneffei infection required differentiation from pneumonia with Pneumocystis jirovecii infection.
