“…If undertreated, it has been observed to result in renal abscess formation. Many of the published cases of this condition have been in the pediatric population and relatively scarce in adults [3,5]. Most of the reported cases of acute lobar nephronia in adults have involved E. coli as the causative organism [4,7].…”

“…Pathologically, it is a focal area of infected kidney without tissue liquefaction [2]. It is thought to represent a disease state midway between tissue inflammation and abscess formation [3]. On radiological imaging, acute lobar nephronia can be mistaken for a neoplastic condition if acute symptoms are not taken into account [4].…”

Acute lobar nephronia is an uncommon type of urinary tract infection affecting the kidneys and more commonly reported in the pediatrics population. It can be a precursor to renal abscess formation if undertreated. Escherichia coli is the commonest pathogen observed in adults with this condition but other organisms have also been reported. This case report describes a 65-year-old woman whose work-up for fever, nausea and vomiting led to the diagnosis of acute lobar nephronia caused by Enterobacter cloacae. The acute lobar nephronia was identified on ultrasound of the kidneys. She was successfully treated with intravenous gentamicin followed by oral ciprofloxacin. Repeat ultrasound showed resolution of the nephronia. This case highlights the need for clinicians to be aware of this condition and ensure appropriate antibiotic treatment to prevent progression into a renal abscess.

“…De este modo el espectro comprendería desde la PNA, NFA simple, NFA compleja, hasta el absceso renal 12 . En dos de nuestros casos, la ecografía mostró alteraciones sugerentes: asimetría renal y/o nefromegalia y riñón "más redondo".…”

“…En relación al perfil clínico, a mayor edad aumenta significativamente el riesgo de desarrollar una lesión focal. En una serie pediátrica publicada por Cheng y cols., la edad promedio de los pacientes con PNA fue de 1,2 años, NFA simple: 2,8 años, NFA complicada: 4,7 años y absceso renal: 6 años 12 . En nuestra serie, las pacientes fueron pre escolares-escolares, con una edad promedio de 5 años y 4 meses.…”
