Sonography in benign and malignant renal masses

Area of Science:

• Radiology
• Medical Imaging
• Nephrology

Background:

• Renal mass lesions are increasingly detected using imaging techniques.
• Ultrasonography (US) and computed tomography (CT) are key modalities for kidney evaluation.
• US is often the initial imaging test for renal lesions, despite limitations in characterization.

Purpose of the Study:

• To provide an overview of benign and malignant renal mass lesions.
• To elucidate the role of ultrasonography in characterizing renal masses.
• To discuss the diagnostic capabilities of US compared to CT for renal lesions.

Main Methods:

• Review of current literature on renal mass characterization.
• Analysis of the diagnostic performance of ultrasonography for renal lesions.
• Comparison of ultrasonography findings with CT and histopathology.

Main Results:

• Ultrasonography demonstrates varying sensitivity and specificity in characterizing renal masses.
• Certain ultrasonographic features can help differentiate benign from malignant renal lesions.
• CT remains crucial for definitive characterization and staging of complex renal masses.

Conclusions:

• Ultrasonography is a valuable initial tool for detecting and evaluating renal masses.
• A combination of imaging modalities, including US and CT, is often necessary for accurate diagnosis.
• Further research is needed to enhance the characterization capabilities of ultrasonography for renal lesions.
