Adrenal cyst misdiagnosed with cystic renal cell carcinoma: A case report.

ABSTRACT: Adrenal cysts are rare adrenal masses that are typically benign and are often incidentally discovered during imaging examinations. However, their complex imaging characteristics can lead to misdiagnosis, particularly when they closely adhere to the upper pole of the kidney, thus resembling renal cysts or cystic renal cell carcinoma (RCC).
