The purposes of this educational exhibit are: To enumerate and categorize the different renal masses and their radiological features; To discriminate between benign and malignant renal lesions.
The detection rate of renal masses has increased in the last decades owing to the widespread use of imaging techniques.
an accurate characterisation is essential to ensure appropriate case management . The approach to a renal mass first begins with an image analysis to be sure that the finding is indeed a true renal mass.
Conditions that mimic a renal mass should be excluded .

Findings and procedure details
Angiomyolipoma Angiomyolipoma (AML) is the most common benign solid renal tumor.
Most AMLs are composed of variable amounts of fat,
smooth muscle and abnormal blood vessels.
AMLs can be associated with tuberous sclerosis (20% of cases). The risk of hemorrhage is related to the size of the tumor,
and it is significantly higher in lesions greater than 4 cm in diameter (Fig 4) . On US,
AML is a circumscribed,
highly reflective mass,
more echogenic than the central sinus fat; renal cell carcinoma...
Owing to the widespread use of abdominal imaging studies,
the detection rate of solid renal masses has increased.
Characterization of imaging features has become essential for management and therapeutic decision-making process. The major question to be answered is whether the mass represents a surgical or nonsurgical lesion or if follow-up studies are necessary.
Careful evaluation of imaging finding combined with the patient's history should assist the radiologist in making the proper diagnosis.
