The mystery behind a 1000 day fever in a young male

This case is of a 23 year old diabetic male who presented with fever and splenic lesions. He continued to have fever off and on over the next 3 years despite empirical antibiotics and anti-tubercular therapy. No definitive diagnosis could be made despite exhaustive investigations. Finally, a splenectomy resulted in sustained defervescence. The splenic histopathology showed caseating granulomas but aerobic cultures, Xpert MTB/Rif ULTRA, TB and fungal cultures were negative. A final diagnosis of splenic melioidosis was made based on the clinical features, radiology, histopathology, literature review and absence of an alternative diagnosis.
