“…6,7 Xanthogranulomatous pyelonephritis is characterized by a chronic infl ammatory process, with destruction of renal parenchyma, subsequently replaced by a granulomatous tissue, containing mononuclear macrophages and lipids (Xanthomam Cells). 8,9 This clinical entity represents 1% of all renal infections. The disease is four times more frequent among women between the fi ftieth and sixtieth decades of life, but can occur at any age.…”

“…Bilateral cases are thought to be fatal. 8,10 Patients with xanthogranulomatous pyelonephritis commonly have diabetes or immunodepression. 3,8 Emphysematous pyelonephritis is a necrotizing infection of the renal parenchyma characterized by the production of gas in the intra-and peri-renal tissues.…”

“…The most common associated infectious agents are Proteus and E. coli, which are responsible for 30-40% of cases. 8 Approximately 10% of patients have negative cultures. 2 In emphysematous pyelonephritis, the most common agents are P. mirabilis, E. coli, and K. pneumonie.…”

“…15 CT scan is now the best tool to diagnose these infections, and it is also important to establish the presence and extension of extra-renal involvement. 4,8,9,12,16 The most frequent fi ndings in the CT scan are calculi, hydronephrosis, kidney enlargement and hypodense areas, with parenchyma destruction. 4,12,13 Other diagnostic methods that can be used in these conditions are voiding cystourethrogram, ultrasound and renal scintigraphy.…”

Pyelonephritis is a pyogenic infection of renal parenchyma that involves the renal pelvis. It is generally of easy diagnosis. The present case report aims to describe two different manifestations of this infection: xanthogranulomatous pyelonephritis and emphysematous pyelonephritis, which have poor prognosis and require a more effective treatment. The two cases were women in the fi ftieth and sixtieth decade of life, with diabetes mellitus and history of weight loss. The diagnosis of the renal infection was established through computed tomography and the treatment was based in surgical procedure, with favorable outcome.

A 35-year-old female presented to her general practitioner with a 1-month history of moderate to severe continuous right flank pain associated with anorexia and weight loss. In the past, she had undergone partial right nephrectomy for a Wilm's tumour at the age of 8 months and was closely followed up for 16 years without recurrence.On clinical examination there was a palpable mass in the right flank extending to the right iliac fossa. Initial work-up revealed a normochromic normocytic anaemia, normal white cell count, normal urea and creatinine, and mildly elevated C-reactive protein of 48. Glomerular filtration rate measured 92 ml min 21, with the right kidney contributing 20% function on dimercaptosuccinc acid scintigraphy. A mid-stream specimen of urine had no white cells, although cultured Escherichia coli.CT (Figure 1) and MRI ( Figure 2) imaging was performed.What was the diagnosis?
