A patient is referred for a renal ultrasound due to suspected cross fused renal ectopia. What is the expected ultrasound finding for this condition?
both kidneys are located on the same side of the body and fused together at varied locations
there is a single kidney located in the midline pelvic region
the kidneys are in their normal position but the upper poles of the kidneys are joined across the midline, usually anterior to the mid AO
the kidneys are in their normal position but the lower poles of the kidneys are joined across the midline, usually anterior to the mid AO
both kidneys are located on the same side of the body and fused together at varied locations
Which of the following correctly describes TCC?
most commonly presents as diffuse bladder wall thickening with multiple masses within the wall
most common mass encountered on the adrenal gland
always causes bilateral hydronephrosis
urinary incontinence is the most common symptom
most commonly presents as diffuse bladder wall thickening with multiple masses within the wall

nephroblastoma
hyperparathyroidism
cholelithiasis
PHTN
nephroblastoma
Oncocytoma, RCC, and FNH share what sonographic characteristic?
thick septations within the mass
posterior enhancement
invasion of vasculature

central scar
Which of the following correctly describes how a Sonographer can differentiate a neuroblastoma from a nephroblastoma on an abdominal US?
it is not possible to differentiate these two tumors sonographically
the neuroblastoma is highly vascular while the nephroblastoma is mainly necrotic due to limited vascular supply
the nephroblastoma will not distort the renal contour or disrupt the capsule, the neuroblastoma will distort the renal contour and disrupt the capsule
the neuroblastoma will not distort the renal contour or disrupt the capsule, the nephroblastoma will distort the renal contour and disrupt the capsule
the neuroblastoma will not distort the renal contour or disrupt the capsule, the nephroblastoma will distort the renal contour and disrupt the capsule
If a pregnant patient has unilateral hydronephrosis, what is the preferred method to rule out an obstructive ureteral calculus as the cause?
apply color Doppler to identify the ureteral jets
obstructive ureteral calculi cannot be evaluated in a pregnant patient, a CT abdomen and pelvis exam with contrast is required
obstructive ureteral calculi cannot be evaluated in a pregnant patient, an intravenous pyelogram is required
ask the patient to empty bladder and apply color Doppler to locate a stone with twinkling artifact
apply color Doppler to identify the ureteral jets
A patient presents for a renal ultrasound due to a recent diagnosis of staphylococcus aureus infection, right flank pain and microscopic hematuria. The chart states the referring physician suspects a renal carbuncle has formed. How will this abnormality be identified sonographically?
a hyperechoic mass of fibrous tissue replaces the tissues of the renal sinus causing significant outflow obstruction
1.5cm complex mass located within the renal pelvis that is causing RV thrombosis
1.5cm complex mass with ringdown and dirty shadowing located within the renal parenchyma
a single large calculus obstructing the renal pelvis with severe hydronephrosis
