81-year-old female patient with abdominal pain. LIVER: The liver measures 15.9 cm in length. No focal hepatic lesion is identified. Main portal vein flow is hepatopetal and measures 0.2 m/sec.GALLBLADDER, BILIARY TRACT: There are no gallstones, gallbladder wall thickening, or pericholecystic fluid. No intra- or extrahepatic biliary ductal dilatation is identified. The common duct measures 5 mm in diameter.PANCREAS: The head and body of the pancreas demonstrate normal echogenicity. Visualized portions of the pancreatic duct measures up to 3 mm in diameter, similar to a prior CT. The tail is obscured by overlying bowel gas.RIGHT KIDNEY: The right kidney measures 10.7 cm in length. No evidence of hydronephrosis. OTHER: The left kidney measures 10.3 cm in length. No evidence of hydronephrosis. There is a 2.1 x 2.2 x 2.4 cm well-defined echogenic lesion within the left lower pole. This is grossly stable in size when compared to prior MR lumbar spines dating back to 11/28/2003, given differences in modality/technique.The spleen measures 6.8 cm in length.
1. No acute sonographic findings to account for the patient's symptoms.2. 2.4 cm echogenic left lower pole renal lesion appears stable in size when compared to MRI lumbar spines dating back to 11/28/2003, given non-dedicated imaging and differences in modality/technique. The length of stability of the lesion favors a benign etiology, possibly an angiomyolipoma.
