case_images: (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.

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

case_images: (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.

case_images: 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).

case_images: (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.

case_images: 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).
