Abstract
- Acute focal bacterial nephritis (AFBN), also called acute lobar nephronia, denotes a focal upper urinary tract infection that is considered to be a midpoint in the spectrum of upper urinary tract infections, ranging from pyelonephritis to renal abscess. AFBN has various imaging findings and should be distinguished from intrarenal abscess or other renal masses. Clinical symptoms are similar to other urinary tract infections but the diagnosis needs a radiologic confirmation, including ultrasonography or computed tomography. Treatment, which is nonoperative, consists of intensive antibiotic therapy. We report a case of AFBN in a 6-month-old female infant who presented with signs and symptoms of a febrile urinary tract infection. Several urine cultures grew Escherichia coli. Ultrasonography, radioisotope study and enhanced computed tomography scan confirmed the diagnosis of AFBN in the lower pole of right kidney. She was treated with intravenous antibiotics for 2 weeks followed by prophylactic antibiotics for 4 weeks. Her renal lesion resolved completely on follow-up examinations.
