Spontaneous Nephrocutaneous Fistula in Xanthogranulomatous Pyelonephritis — A Rare Complication

The formation of fistulous tract between the kidney and adjacent organs is not uncommon while cutaneous fistulization is a rarer occurrence. We present a case of Nephrocutaneous Fistula without prior history of surgery or interventional procedure. Our case involves long standing obstructive pyonephrosis secondary to obstructing calculus at the ureteropelvic junction which led to formation of a fistulous tract upto the skin surface. This patient had complaints of purulent discharge from the right flank region associated with fever spikes since the last 1 month. The cutaneous manifestation in specific location should raise the possibility of underlying renal pathology

Pyloric wall thickening in carcinoma stomach: a pseudokidney sign on computed tomography.

Bowel wall thickening on ultrasound simulates appearance of kidney. The appearance of kidney on contrast enhanced computed tomography is entirely different. However, surprisingly bowel wall thickening or mass can mimic this appearance even on contrast enhanced computed tomography. A case of pyloric malignancy with pseudokidney appearance on contrast enhanced computed tomography is being reported.
