Objectives: After studying the article entitled “Imaging Features of Renal Capsule Leiomyoma on Contrast-Enhanced Ultrasonography: A Case Report,” you will be able to
Demonstrate the use of contrast-enhanced ultrasound (CEUS) to delineate a leiomyoma of the kidney.
Discuss the imaging features of a leiomyoma attached to a kidney that is highlighted with ultrasound contrast perfusion.
Identify the kinetic behavior of ultrasound contrast in a leiomyoma of the kidney.
The reported patient was given what dose of CEUS for imaging the computed tomography (CT) -detected renal lesion? 2.4 mL Sonoview drip infusion with a saline flush 2.4 mL bolus injection of Sonoview with a saline flush 5 mL bolus injection of Sonoview without a saline flush 5 mL Sonoview drip with a bolus of saline as flush for the IV
The lesion’s time-intensity curve (TIC) analysis of the ultrasound contrast behavior was deemed hypervascular with which of the following values? 6.90 intensity units 1.17 intensity units 1.20 intensity units 3.80 intensity units
Which of these imaging features is typically seen on a CT scan of a renal leiomyoma? Poorly marginated High-density lesion Exophytic Evidence of extrarenal invasion
According to the TIC data displayed in Figure 4, how does the contrast in the tumor compare to the surrounding anatomy? Tumor contrast enhancement > the transplanted kidney Tumor contrast enhancement < the native kidney Tumor contrast enhancement > the native kidney Tumor contrast enhancement = the transplanted kidney
What is the risk of malignancy among renal transplant patients? 10 times greater than the general population 5 times greater than the general population 2-4 times greater than the general population 24 times less than the general population
