    Summary
    This summary is machine-generated.

    Extrahilar renal vessel entry can cause renal margin defects, a previously unreported radiographic finding. Urography identified these defects, which may be misdiagnosed without further imaging like arteriography.

    Area of Science:

    • Radiology
    • Urology
    • Anatomy

    Background:

    • Extrahilar renal vessel entry is a known anatomical variation.
    • Radiographic identification of its consequences has not been previously documented.
    • Renal margin defects can mimic other pathologies.

    Observation:

    • Three patients presented with renal margin defects on urography.
    • These defects were secondary to extrahilar entry of renal vessels.
    • This finding was previously unreported in radiographic literature.

    Findings:

    • Extrahilar renal vessel entry can manifest as a renal margin defect on urography.
    • This finding may be mistaken for persistent fetal lobulation or renal scarring.
    • Arteriography may be required for accurate diagnosis.

    Implications:

    • Recognizing this radiographic finding improves diagnostic accuracy.
    • It aids in differentiating vessel anomalies from other renal conditions.
    • This knowledge is crucial for urologists and radiologists.
