title: Acute pyelonephritis simulating poorly vascularized renal neoplasm. Non-specificity of angiographic criteria.
abstract: A case of acute pyelonephritis associated with venous encasement and amputation is described. Although venous encasement and amputation have been considered previously as specific signs of malignancy, it is now clear that these signs are non-specific, occurring also in inflammatory diseases of the kidney.
