Upper quadrant pain B. Asymptomatic C. Radiating pain D. Hematura - CORRECT ANSWER B. Asymptomatic However, large, infected, or hemorrhagic cysts can cause pain Accessory adrenal gland tissue found within the testes, epi, ovaries, and inguinal canal are called: - CORRECT ANSWER adrenal rests -associated w/ congestive adrenal hyperplasia and Cushing syndrome The adrenal glands are the ____ most common site of metastasis A. First B. Fourth C. Tenth D. The properties of the gland do not allow mets - CORRECT ANSWER B. Fourth Cancer of the adrenal _______ (cortex/medulla) tends to be large and invade adrenal vein and IVC - CORRECT ANSWER cortex This type of adrenal malignancy can mimic symptoms of Cushing syndrome and appearance of an adenoma. What is its sono appearance? - CORRECT ANSWER Adrenal carcinoma Sono: -solid, hypoechoic mass -large, heterogeneous mass Solid, large (average 8cm), heterogeneous mass arising from the adrenal medulla - CORRECT ANSWER Neuroblastoma A one year old infant presents to the department with a palpable abdominal mass, abdominal pain, and bone pain. You see a 10 cm mass in the abdomen between the right kidney and liver. What is this most likely to be? - CORRECT ANSWER Neuroblastoma of the adrenal gland This can happen to the adrenal glands after a traumatic birth or perinatal anoxia - CORRECT ANSWER Adrenal hemorrhage You see a rounded echogenic mass on a neonatal adrenal gland. You scan them again 3 days later and it is now heterogenous and hypoechoic. What are you thinking? - CORRECT ANSWER Hematoma secondary to adrenam hemorrhage Abdominal mass, jaundice, anemia, and an acute drop in hematocrit and blood pressure associated with the adrenal gland is indicative of: - CORRECT ANSWER adrenal hemorrhage Hormone responsible for regulating blood pressure by controlling the amounts of sodium and water in the body? A. Epinephrine B. Cortisol C. Aldosterone D. ACTH - CORRECT ANSWER C. Aldosterone The most common sonographic appearance of a neuroblastoma is: A. Hyperechoic mass B. Heterogeneous mass w/ calcs C. Anechoic mass D. Hypoechoic mass - CORRECT ANSWER B. Heterogeneous mass with calcifications The most common sonographic appearance of a pheochromocytomas is a(n): A. hyperechoic mass B. hypoechoic mass C. anechoic mass D. complex mass - CORRECT ANSWER A. Hyperechoic mass Which of the following abnormalities is associated with the production of milk of calcium bile A. hepatoma B. cirrhosis C. acute cholecystitis D. chronic cholecystitis - CORRECT ANSWER D. Chronic cholecystitis Varicoceles are more common on what side? Due to the relationship of the gonadal vascular anatomy to surrounding structures - CORRECT ANSWER left. It can be caused by nutcracker syndrome b/c the left renal vein is compressed by SMA and ao, which decreases drainage If a tumor ablation in the liver is performed and then contrast enhanced US is used. Will there be contrast uptake? - CORRECT ANSWER No -- ablation eliminates blood supply so a normal lesion will not take in contrast intraperitoneal accumulation of gelatinous ascites secondary to rupture of mucinous tumor. Commonly caused by ruptured mucinous tumor of appendix - CORRECT ANSWER Pseudomyxoma peritonei Potential collateral pathway where blood moves from coronary and short gastric veins into the esophageal veins. This is associated with: - CORRECT ANSWER cirrhosis the aorta is _______ to the left and right crura of the diaphragm while the ivc is ________ to the right crus - CORRECT ANSWER posterior;anterior [Show More]
