AND ANSWERS
The process of disposing metabolic wastes is called: - Answer- excretion
A cortical bulge in the lateral border of the kidney is called a(n): - Answer- dromedary
hump
An extremely large echogenic renal sinus that appears to engulf the entire renal
parenchymal outline suggests - Answer- lipomatosis
A triangular-shaped defect located anteriorly in the upper pole of the kidney most likely
represents a(n): - Answer- junctional parenchymal defect
The left renal vein courses: - Answer- anterior to the aorta
The most common solid renal mass found in childhood is: - Answer- wilms' tumor
Renal cell carcinoma commonly invades the IVC via the: - Answer- renal vein
Papillary necrosis may develop within ________ after renal transplantation - Answer-

A 65-year-old patient with a history of abdominal pain and gas is seen for an abdominal
and pelvic ultrasound scan. The laboratory results included hematuria. Ultrasound
examination of the abdomen reveals a slightly enlarged spleen and a solid right renal
upper pole mass (Figure 1,A and B). No hydronephrosis is identified, and the right renal
vein and inferior vena cava are patent. A computed tomographic (CT) scan is performed
to further evaluate the right renal mass. What is the most likely differential
consideration? - Answer- renal cell carcinoma
