ABSTRACT

Acute lobar nephronia is a focal of acute bacterial nephritis, affecting one or more of the renal lobules. Nephronia is being diagnosed more frequently in accordance with the advancing imaging techniques of urinary tract. We report a case of acute nephronia in a 4 month old boy who presented persisting urinary tract infection after intial antibiotic treatment. Ultrasonography and computerized tomography showed round wedge-shaped, non-enhancing mass in right kidney. Gallium scan also revealed the lesion in the right kidney. This lesion resolved completely on one month follow up examinations. (J. Korean Soc Pediatr Nephrol 5 : 73- 7, 2001)
