Abstract
Introduction After identifying and correcting pitfalls related to image acquisition, radiologists should focus their attention on the potential errors that can occur during image interpretation. Among them, thefirst andmost important one is inappropriate characterization of a focus of normal renal tissue, congenital variant, or a benign infectious or inflammatory condition as a renal neoplasmon imaging studies. Secondly, identification of fat within a solid renalmass can create problems in distinguishing benign angiomyolipoma (AML) from malignant entities such as renal cell carcinoma (RCC) and liposarcoma. Thirdly, inappropriate assessment of contrast enhancement in solid or cystic masses, especially in hyperattenuating and heavily calcified renal masses, may pose significant problems that result in a faulty interpretation of a benign neoplasm as a malignant one and vice versa. In this article, we would review potential errors that radiologistsmay encounter during interpretation of ultrasound (US), multiple detector computed tomography (MDCT), and magnetic resonance imaging (MRI) studies in patients with renal masses and provide possible solutions to overcome these pitfalls.
