Abstract:
We present three patients, aged 4, 6 and 8 years old, with a diagnosis of urinary tract infection. In all patients, initial ultrasonographic studies revealed a single area of acute lobar nephronia (ALN). The patients underwent renal scintigraphy with dimercaptosuccinic acid-99mTc (DMSA Tc 99m), which showed multiple foci with below normal uptake in both kidneys of two patients, consistent with bilateral multifocal bacterial nephritis. Although this entity has been reported together with ALN in adults, very few pediatric cases have been reported. We emphasize the diagnostic value of ultrasonography and renal scintigraphy.
