    Summary

    This study correlates sonographic findings of hypernephromas with other diagnostic methods. It highlights criteria for identifying challenging hypoechoic tumors that may mimic cysts.

    Area of Science:

    • Radiology
    • Medical Imaging
    • Oncology

    Background:

    • Hypernephromas (renal cell carcinomas) can present diagnostic challenges.
    • Sonographic features may overlap with other renal lesions, like cysts.
    • Angiography may not always reveal tumor neovascularity, complicating diagnosis.

    Purpose of the Study:

    • To characterize sonographic appearances of hypernephromas.
    • To correlate these findings with angiographic and pathologic data.
    • To establish criteria for differentiating hypoechoic tumors from cysts.

    Main Methods:

    • Sonographic examination of 43 confirmed hypernephromas.
    • Correlation with angiographic and pathological findings.
    • Analysis of diagnostic criteria for hypoechoic renal masses.

    Main Results:

    • Specific sonographic criteria were identified for hypernephromas.
    • Poorly echogenic tumors can mimic cysts, posing a diagnostic dilemma.
    • Absence of neovascularity on angiography does not exclude malignancy.

    Conclusions:

    • A correlative approach using clinical, urographic, sonographic, and angiographic data is essential for accurate diagnosis.
    • Recognizing subtle sonographic signs is crucial for differentiating hypernephromas from cysts.
    • Integrated diagnostic work-up improves diagnostic accuracy for renal tumors.
