Figure 1: A retroperitoneal incidentaloma in a 63-year-old female patient with a urinary tract infection. (a) Transverse sonogram of the upper abdomen shows a mass lesion (arrows) with central cystic change in the left upper retroperitoneum, behind the pancreas (p). (b) Color Doppler (left panel, velocity setting of 53 cm) and corresponding gray-scale (right panel) transverse sonograms at the level of the celiac artery (CA) show the mass (m) in the left lateral to the abdominal aorta (AA). The mass lesion is thought to be in the left adrenal fossa. No detectable Doppler flow signal within the lesion. (c) Color Doppler (left panel) and corresponding gray-scale (right panel) longitudinal sonograms reveal that the mass (marked by + cursors) is posterior to the splenic vein (SV) and caudal (distal) to the splenic artery (SA) and between the liver (l), spleen (s), and left kidney (LK). HA, hepatic artery; IVC, inferior vena cava; PV, portal vein; VB, vertebral body
