1/9. Focal bacterial nephritis (lobar nephronia) presenting as renal mass.A focal infection of the kidney can cause a diagnostic dilemma by mimicking a neoplasm. We describe a case of focal bacterial nephritis (acute lobar nephronia) caused by escherichia coli in which the diagnosis was confirmed only after surgical exploration. Although the patient had fever on admission, urine and blood cultures were negative and fine needle aspiration of the kidney could not rule out a well-differentiated carcinoma.- - - - - - - - - - ranking = 1keywords = nephritis (Clic here for more details about this article) |
2/9. Acute focal bacterial nephritis in an 8-year-old .Acute focal bacterial nephritis or acute lobar nephronia is an acute localized non-liquefactive bacterial kidney infection. Clinically, it may develop as an abscess and present as acute pyelonephritis but is distinguishable by the presence of a focal mass on imaging studies. The authors report the case of an 8-year-old girl with fever up to 39 degrees C and left flank pain of 6 days duration. On physical examination, she had nothing remarkable except tenderness and knocking pain over the left costovertebral angle. Post-contrast abdominal computed tomography revealed several wedge-shaped hypodense lesions in the left kidney. urine culture grew escherichia coli. Acute focal bacterial nephritis was diagnosed. The patient was treated with antibiotics and discharged on the 12th day of hospitalization.- - - - - - - - - - ranking = 1.4keywords = nephritis (Clic here for more details about this article) |
3/9. Migratory lobar nephronia.Lobar nephronia or focal bacterial nephritis is a pre-abscess stage of localized cellulitis and has been shown to represent a focal imaging manifestation of what is frequently a diffuse renal process. To the best of our knowledge, although multi-focal bacterial nephritis has been described, a migratory pattern has not been observed. This report describes a previously healthy 32-year-old woman with pathologically proven lobar nephronia that exhibited a migratory pattern on serial computed tomography (CT) and a prolonged course on antibiotic therapy. Possible etiologies for this unusual course, along with the CT, sonographic and needle biopsy features of this disease are discussed.- - - - - - - - - - ranking = 0.4keywords = nephritis (Clic here for more details about this article) |
4/9. Acute focal bacterial nephritis and renal abscess associated with vesicoureteral reflux. Report of a case.We report the case of a child with acute focal bacterial nephritis and a renal abscess in the right kidney associated with bilateral vesicoureteral reflux. The patient was treated successfully with antibiotics and bilateral ureterocystoneostomy. urine has remained sterile since the operation, but the affected kidney has developed progressive scarring. This case suggests that acute focal bacterial nephritis and a renal abscess may cause a small kidney, which looks like a hypoplastic kidney, associated with vesicoureteral reflux.- - - - - - - - - - ranking = 1.2keywords = nephritis (Clic here for more details about this article) |
5/9. Acute focal bacterial nephritis presented as acute renal failure and hepatic dysfunction in a renal transplant recipient.We describe acute focal bacterial nephritis (AFBN) presented as acute renal failure and hepatic dysfunction in a renal transplant recipient. He had received a renal transplantation 5 years previously and maintained good renal function without an episode of acute rejection or any urinary abnormalities. He had been an HBsAg carrier and showed mild elevation of liver enzymes after renal transplantation. For 5 days before admission, the patient suffered from fever, graft kidney swelling, tenderness and oliguria. On admission, renal biopsy was performed and solumedrol pulse therapy was started under the impression of acute rejection. The following laboratory findings revealed acute renal failure and hepatic dysfunction. From the abdomen CT and renal biopsy findings this case was confirmed as AFBN in a grafted kidney. With successive hemodialysis and antibiotic therapy clinical symptoms and renal function improved promptly. In acute hepatic dysfunction we discontinued cyclosporine (CsA) to prevent irreversible fulminant hepatic failure until the normalization of liver function. It should be considered that AFBN must be included in the differential diagnosis of acute rejection, and the early diagnosis and treatment of AFBN is important to save the grafted kidney. In addition, early withdrawal of CsA is essential to prevent irreversible hepatic failure when infection triggers hepatic dysfunction in HBsAg-positive renal transplant recipients.- - - - - - - - - - ranking = 1keywords = nephritis (Clic here for more details about this article) |
6/9. Imaging studies on acute focal bacterial nephritis.Two cases of acute focal bacterial nephritis (AFBN) are reported. The first patient was a 35-year-old man and the diagnosis was made by ultrasonography (US) and computed tomography (CT). The second patient was a 40-year-old man and was diagnosed by US, CT and renal biopsy. They were treated with antibiotics and showed rapid improvement in both clinical symptoms and renal masses.- - - - - - - - - - ranking = 1keywords = nephritis (Clic here for more details about this article) |
7/9. Acute lobar nephronia: a case report.Acute lobar nephronia (ALN), a term analogous to acute lobar pneumonia, refers to a renal mass caused by acute focal infection without liquefaction. An alternative term is acute focal bacterial nephritis (AFBN). fever, flank pain or back pain are the most frequently encountered clinical characteristics. Imaging modalities used to establish a definite diagnosis of acute lobar nephronia included sonography, computed tomography and nuclear medicine. Uroradiographic findings in this condition can mimic a renal abscess or neoplasm. Further distinction between acute lobar nephronia and other renal masses is aided by the appropriate use of renal sonography and computerized tomography is the most effective and least costly method in diagnosis. Serial sonograms can be used to monitor response to antibiotic therapy. Clinical and uroradiographic characteristics of a six year-old female patient with acute lobar nephronia are presented, along with a review of literature.- - - - - - - - - - ranking = 0.2keywords = nephritis (Clic here for more details about this article) |
8/9. Acute lobar nephronia of renal transplant allograft.Acute lobar nephronia (acute focal bacterial nephritis) has recently been recognized as an infectious process of the kidney. It is a radiologic diagnosis characterized as a nonliquifiable inflammatory renal mass associated with signs and symptoms of bacterial pyelonephritis. We present the successful management of a renal allograft recipient who had radiologic evidence of acute lobar nephronia within the graft six weeks after placement of an internalized ureteral stent.- - - - - - - - - - ranking = 0.4keywords = nephritis (Clic here for more details about this article) |
9/9. Acute focal bacterial nephritis in childhood brucellosis.brucellosis is an infectious disease transmitted from various animal hosts to man. In children the most common route of infection is unpasteurized milk or milk products. brucellosis affects the urinary tract uncommonly, most frequently causing orchioepididymitis. We report the case of a 4-year-old boy with brucellosis who developed acute focal bacterial nephritis (AFBN), documented by sonography, gallium scan, and computed tomography. After appropriate treatment his symptoms and his sonographic abnormality resolved completely. To the best of our knowledge, this is the first report of the association of AFBN and brucellosis.- - - - - - - - - - ranking = 1keywords = nephritis (Clic here for more details about this article) |
