Renal adenocarcinoma in benign hyperdense mass

Area of Science:

• Nephrology
• Oncology
• Radiology

Background:

• Renal masses can present with varying imaging characteristics.
• Hyperdense renal masses on computed tomography (CT) can pose diagnostic challenges.
• Distinguishing benign from malignant hyperdense renal masses is crucial for patient management.

Purpose of the Study:

• To report a case of renal adenocarcinoma mimicking a benign hyperdense renal mass.
• To review the potential etiologies of hyperdense renal masses.
• To outline the radiologic diagnostic criteria for hyperdense renal masses.

Main Methods:

• Case presentation of a patient with a hyperdense renal mass.
• Review of relevant literature on renal mass imaging.
• Analysis of radiologic features differentiating benign and malignant hyperdense masses.

Main Results:

• A renal adenocarcinoma was identified despite presenting as a benign hyperdense mass.
• Etiologies for hyperdense renal masses include hemorrhage, calcification, and proteinaceous fluid.
• Radiologic findings suggestive of malignancy in hyperdense masses were analyzed.

Conclusions:

• Renal adenocarcinoma can present atypically as a benign hyperdense mass.
• Comprehensive radiologic evaluation is essential for accurate diagnosis of hyperdense renal masses.
• Early detection and appropriate management are key for improved patient outcomes in renal cell carcinoma.
