Questions: 5: Knowledge Check Describe what you see on the image below: Echogenic mass located in cortical area of the kidney inferior end Solid mass located superior pole of kidney Complex mass located in cortical area of the kidney superior end Solid mass located inferior pole of kidney

Solution Steps

The ultrasound image shows a solid, homogenous mass located at the lower portion of the kidney. The arrow points directly at the mass. Now let's look at the options. The first option mentions the inferior end which does align with the image. Option 2 points to the superior pole, which is wrong. Option 3 says superior end, so it's also wrong. Option 4 points to the inferior pole which is also incorrect.

The terms "pole" and "end" have different meanings in renal anatomy. "Pole" refers to the rounded extremities of the kidney (superior and inferior poles), while "end" can be a more general term but here signifies the inferior extremity. Considering that the mass appears to be within the renal parenchyma and not directly at the rounded inferior pole, "inferior end" is the most accurate description of its location.

The mass appears uniformly bright or hyperechoic, making "echogenic" an appropriate descriptor. The mass does not appear to contain cystic or other mixed echogenicity components, therefore "solid" accurately represents its composition as opposed to "complex."

Final Answer: The first option is correct: Echogenic mass located in cortical area of the kidney inferior end.
