Pseudotumor of kidney

R S Rankin, J D Wegenke, P O Madsen

    Urology
    |July 1, 1977
    PubMed
    Summary

    Pyelocancerous backflow during retrograde pyelography can indicate renal tumors but is not specific. Renal hematomas can also cause this radiographic sign, highlighting the need for careful diagnosis.

    Area of Science:

    • Radiology
    • Urology
    • Nephrology

    Background:

    • Retrograde pyelography is a common diagnostic tool in urology.
    • Pyelocancerous backflow is a recognized radiographic sign suggestive of renal tumors.

    Observation:

    • A case of intrarenal hematoma, secondary to anticoagulation therapy, mimicked pyelocancerous backflow.
    • This pseudotumor demonstrated the nonspecific nature of the backflow sign.

    Findings:

    • The study discusses the diagnostic and radiographic findings associated with intrarenal hematomas.
    • Radiographic features of renal hematoma can overlap with those of renal tumors.

    Implications:

    • The findings underscore the importance of considering differential diagnoses when interpreting radiographic signs.
    • Accurate differentiation between renal tumors and hematomas is crucial for appropriate patient management and treatment planning.
