Renal microabscesses due to Bartonella infection.

We report a case of cat scratch disease with bilateral renal microabscesses. This case is unique in that there were no other abscesses found intrabdominally. A previously healthy child was admitted with a 12-day history of fever and headaches. Bartonella henselae titers were initially IgG 1:640 and IgM 1:100, and later IgG >1:2560 and IgM >1:800. An abdominal ultrasound examination was normal but CT scan revealed microabscesses in both kidneys.
