Associate clinical findings and symptoms with sonographic findings of neuroblastoma
Approximately how many new cases of neuroblastoma are diagnosed in the United States each year? 150–200 450–500 600–650 900–950
Approximately what percentage of abdominal neuroblastomas are located in the adrenal medulla? 55%–60% 65%–70% 75%–80% 85%–90%
The majority of neuroblastomas occur in which age group? 2–3 years old 5–6 years old 8–9 years old 13–14 years old
To what organ is neuroblastoma most likely to metastasize? Liver Brain Lung Skin
Neuroblastoma occurs bilaterally in cases with what frequency? <5% 20%–25% 30%–40% 40%–50%
A neuroblastoma localized to the adrenal medulla will typically cause what symptom? Fever Bone pain Failure to thrive None; usually asymptomatic
Prenatal neuroblastoma is usually detected by sonography at what stage of pregnancy? Mid second trimester Late second trimester Mid third trimester Late third trimester
Which of the sonographic characteristics below is not a typical finding for a neuroblastoma of the adrenal medulla found postnatally? A mass effect displacing the ipsilateral kidney, aorta, and inferior vena cava An anechoic cystic structure involving the renal cortex Color Doppler imaging demonstrating hyperemia Interior calcification with posterior shadowing
