Probable PJP in an Immunosuppressed Host

This is a case report of a 68 year old immunosuppressed female patient due to rheumatoid arthritis, who developed fever, cough & breathlessness with desaturation. HRCT chest showed bilateral ground glass opacities with peripheral sparing. S beta-D-glucan & S LDH were high. Therefore, the patient was diagnosed to have probable Pneumocystis jirovecii pneumonia and treated with cotrimoxazole (later changed to primaquine/clindamycin due to ADRs) & a tapering dose of corticosteroids. She had complete clinical & radiological recovery.
