A 70-year-old male with recurrent UTIs undergoes a renal ultrasound. Images demonstrate multiple fluid-filled structures located within the renal sinus that do not communicate with each other or with the infundibula/renal pelvis. What pathology is most consistent with these findings?

What ultrasound findings are commonly seen as a result of end-stage Chronic Kidney Disease?

A 40-year-old female is found to have multiple, renal cortical masses appearing similarly to the mass seen in this image. What benign tumor is this most consistent with?

An adult male patient is referred for a renal scan due to elevated blood pressure. Sonography reveals a left kidney measuring 6.1 cm in length with normal cortical echogenicity and architecture. The right kidney measures 14.2 cm in length with normal echogenicity. What diagnosis is most consistent with these sonographic findings?

What is the most common primary malignant tumor of the urinary bladder?

This 23 year old female was referred to the ultrasound department for a renal ultrasound. Her history is significant for recurrent urinary tract infections, vesicoureteric reflux and moderately elevated BUN and creatinine serum levels. What pathologic process is demonstrated below?

Match each labeled structure on the ultrasound image with the correct anatomical term.  

An asymptomatic 35-year-old female presents with a focal, prominent bulge of cortical tissue along the lateral aspect of the mid-pole of the left kidney. The tissue is iso-attenuating and continuous with the rest of the renal cortex. What normal renal finding is most consistent with this presentation?

What is the most common primary solid renal malignant neoplasm in adults?

An asymptomatic 28-year-old female undergoes an abdominal sonogram. A triangular, hyperechoic notch is visualized along the anterior superior pole of the right renal cortex. This normal anatomical variant, formed by the incomplete fusion of embryonic ranunculi, is termed a [x]. (Must be spelled correctly for full credit).
