Findings of the imaging studies. A select axial image of a noncontrast abdominal computed tomographic scan (A) shows a solid mass with hypodense appearance deforming the contour in the upper pole of the left kidney (arrowhead). Note that the PD catheter within the wall of the abdomen is indicated (arrow). A longitudinal gray-scale ultrasound image (B) reveals a hypoechoic round shape mass in the corresponding region of the left kidney, whereas a peripheral vascular distribution with some penetration is demonstrated on color Doppler flow mapping (C).

A 75-year-old woman who had been treated with PD for 2 years because of ESKD secondary to chronic glomerulonephritis was incidentally found to have a solid mass measuring 20 mm in its greatest dimension in the upper pole of the left kidney without any findings of lymphadenopathy by abdominal computed tomography performed as the annual surveillance (Figure 1A), and the subsequent renal sonographic analysis revealed the hypoechoic mass associated with a peripheral vascular distribution in the corresponding region (Figure 1B and 1C).
