title: Pseudotumor of kidney.
abstract: Pyelocancerous backflow during retrograde pyelography is a roentgen sign indicating renal tumors. An example of a pseudotumor (renal hematoma caused by anticoagulation) is presented which displayed this type of backlfow, demonstrating the nonspecificity of the sign. The diagnostic, especially radiographic, findings of intrarenal hematoma are discussed.
