Brucellosis as a Cause of Unilateral Sacroiliitis in a Haemodialysis Patient

Brucellosis is a zoonotic disease with multiorgan involvement.Though endemic in South Asia including Pakistan, its diagnosis is often delayed because of unawareness.Herein, a case is presented of a male patient who was previously admitted and treated for culture-negative infective endocarditis in a tertiary care hospital.He later presented with Brucella sacroiliitis that responded to triple antibiotics.This case not only highlights Brucella as a cause of sacroiliitis but also points towards the importance of proper evaluation of culture-negative infective endocarditis, as retrospectively the culture-negative endocarditis in this patient was most probably caused by Brucella.
