(a) Point-of-care ultrasound image of the right kidney in an asymptomatic
54-year-old woman shows a peripherally located isoechoic solid mass
(arrow) causing distortion of the renal border. (b) Formal renal
ultrasonography image of 1 (arrow) of 2 solid masses found in the
inferior pole of the right kidney, the largest measuring 4.6 cm in its
biggest dimension. (c) Contrast-enhanced computed tomography imaging of
the abdomen and pelvis, coronal view shows a peripheral, likely
multifocal renal cell carcinoma (arrow) in the inferior pole of the
right kidney.

POCUS demonstrated a renal mass adjacent to the right kidney (Figure 1).

(a) Point-of-care ultrasound image of the left kidney in an asymptomatic
63-year-old man shows a large isoechoic solid mass measuring
approximately 6 cm in its largest dimension. (b) Formal renal
ultrasonography image of the left kidney showing distortion of normal
renal architecture with a centrally located heterogeneous solid mass.
(c) Contrast-enhanced computed tomography imaging of the abdomen and
pelvis, coronal view shows an 8 cm x 5.5 cm x 8 cm heterogeneously
enhancing mass consistent with renal cell carcinoma in the left kidney,
as well as a simple renal cyst in the superior pole of the left kidney.
Three months after these images were obtained, the patient developed
gross hematuria.

Formal renal ultrasound performed 12 days later confirmed a centrally located 6.2-cm solid mass in the left kidney suggestive of renal cell carcinoma (Figure 2).

(a) Point-of-care ultrasound image of right kidney in an asymptomatic
69-year-old man with a history of tobacco use shows a heterogeneous
solid mass measuring approximately 3 cm in its largest dimension. (b)
Formal renal ultrasonography image of a peripherally located solid mass
(arrow) found in the right kidney, measuring 3 cm in its largest
dimension. This mass demonstrated increased blood flow (not pictured)
consistent with renal cell carcinoma. (c) Contrast-enhanced computed
tomography imaging of the abdomen and pelvis, coronal view shows a
peripheral mass (arrow) on the right kidney with no evidence of renal
vein involvement or metastatic disease in the rest of the abdomen.

Formal renal ultrasonography with Doppler was obtained 15 days later and confirmed the presence of a 3-cm solid mass in the right kidney with demonstrable blood flow consistent with renal cell carcinoma (Figure 3).
