Nephrocutaneous Fistula due to Xanthogranulomatous Pyelonephritis.

Cureus 2018 Oct 19;10(10):e3467. Epub 2018 Oct 19.

Internal Medicine, Staten Island University Hospital, Staten Island, USA.

While the development of a fistulous tract from the kidney to the proximal adjacent organs is relatively common, a tract leading to the skin is a rare occurrence. The primary cause of a fistula is prior surgical intervention or malignancy leading to abscess formation. Our case involves Xanthogranulomatous pyelonephritis (XGP) causing a longstanding lobulated abscess, ultimately leading to the formation of a fistulous tract. Read More

Ancillary studies in fine needle aspiration of the kidney.

Cancer Cytopathol 2018 Aug;126 Suppl 8:711-723

Baptist Hospital of Miami and Miami Cancer Institute, Miami, Florida.

An increasing number of renal cell carcinomas (RCCs) require ancillary studies for diagnosis. The majority of renal fine needle aspirates do not require ancillary studies. Among the most common useful stains are cytokeratin 7 (separating clear cell RCC [negative] from papillary RCC, clear cell papillary RCC, and multilocular cystic RCC [positive] as well as separating chromophobe RCC [diffusely positive] from oncocytoma [focally positive/negative]) and CD117 (separating chromophobe RCC and oncocytoma [positive] from granular variants of clear cell RCC [negative]).

Pyeloduodenal Fistula in Xanthogranulomatous Pyelonephritis: A Series of Two Cases.

Perm J 2018 ;22:17-150

Surgeon in the Division of Transplant Surgery and the Division of Acute Care Surgery and Trauma at Memorial Regional Hospital in Hollywood, FL.

Xanthogranulomatous inflammation, characterized by destruction and replacement of tissues with chronic inflammatory cells, including foamy histiocytes and hemosiderin-laden macrophages, is uncommon. In patients with xanthogranulomatous pyelonephritis, inflammation may extend from the kidney to the overlying duodenum, creating a pyeloduodenal fistula that further complicates medical and surgical management. We present two cases with recurrent kidney infections who each ultimately received a nephrectomy and repair of their duodenal fistula. Read More

From the Department of Radiology, Virginia Commonwealth University Medical Center, 1250 E Marshall St, PO Box 980615, Richmond, VA 23298.

A variety of entities may mimic drainable abscesses. This can lead to misdiagnosis of these entities, unnecessary percutaneous placement of a pigtail drainage catheter, other complications, and delay in appropriate treatment of the patient. Types of entities that may mimic drainable abscesses include neoplasms (lymphoma, gallbladder cancer, gastrointestinal stromal tumor, ovarian cancer, mesenteric fibromatosis, ruptured mature cystic teratoma, recurrent malignancy in a surgical bed), ischemia/infarction (liquefactive infarction of the spleen, infarcted splenule), diverticula (calyceal, Meckel, and giant colonic diverticula), and congenital variants (obstructed duplicated collecting system).

CT imaging spectrum of infiltrative renal diseases.

Abdom Radiol (NY) 2017 11;42(11):2700-2709

Department of Radiology, Louisiana State University Health Shreveport, 1501 Kings Hwy, Shreveport, LA, 71103, USA.

Most renal lesions replace the renal parenchyma as a focal space-occupying mass with borders distinguishing the mass from normal parenchyma. However, some renal lesions exhibit interstitial infiltration-a process that permeates the renal parenchyma by using the normal renal architecture for growth. These infiltrative lesions frequently show nonspecific patterns that lead to little or no contour deformity and have ill-defined borders on CT, making detection and diagnosis challenging. Read More
