Test on Radiology of Retroperitoneal and Urogenital Pathologies

Question 1: Smoking, hypertension, and obesity are identified as risk factors for Renal Cell Carcinoma.

A. Ano

B. Ne

Explanation: The study materials explicitly state that smoking, hypertension, and obesity are risk factors for Renal Cell Carcinoma under the 'Incidence' section for RENAL CELL CARCINOMA.

Question 2: Which of the following describes the ultrasound appearance of bladder stones?

A. Echogenic mobile structures that produce posterior acoustic shadowing.

B. Hypoechoic, non-mobile masses without shadowing.

C. Anechoic structures with thickened walls.

D. Echogenic, non-shadowing masses that are typically fixed in location.

Explanation: Bladder stones appear as echogenic mobile structures that produce posterior acoustic shadowing. A higher-frequency transducer can be used for small stones to better visualize the shadowing. Other options describe different pathologies or incorrect features.

Question 3: On ultrasound, Adult Polycystic Kidney Disease typically shows unilateral enlarged kidneys.

A. Ano

B. Ne

Explanation: The study materials state that Adult Polycystic Kidney Disease (APKD) ultrasound findings include "Bilateral enlarged kidneys" and "Multiple cysts of variable size", not unilateral involvement.

Question 4: According to the provided study materials, which of the following sonographic features are characteristic of Renal Medullary Necrosis?

A. Echogenic calculi with shadowing

B. Multiple cysts of variable size

C. Enlarged kidneys with hyperechoic pyramids

D. No specific sonographic features are described in the provided materials for this condition

Explanation: The study materials describe symptoms such as hematuria and sloughed papillae in the urine for Renal Medullary Necrosis, but do not provide any specific sonographic features for this condition. Echogenic calculi with shadowing are described for Medullary Nephrocalcinosis. Multiple cysts of variable size are characteristic of Adult Polycystic Kidney Disease. Enlarged kidneys with hyperechoic pyramids are associated with Acute Tubular Necrosis (ATN) or Acute Renal Failure.

Question 5: The most common manifestation of Von Hippel-Lindau disease is neuroblastoma.

A. Ano

B. Ne

Explanation: For Von Hippel-Lindau disease, the most common manifestation is kidney cancer (Wilms tumor), not neuroblastoma.
