58-year-old male patient with previously noted hypoechoic region adjacent to the gallbladder fossa. Urination hourly, nocturia x3. Assess for hydronephrosis. LIVER:The liver measures 15.0 cm in length and demonstrates increased parenchymal echogenicity. A region of hypoechogenicity adjacent to the gallbladder fossa measures approximately 3.7 x 3.0 cm, similar to the prior study, and likely represents focal fatty sparing. Main portal vein flow is hepatopetal and measures 0.2 m/s.GALLBLADDER, BILIARY TRACT: No gallstones, gallbladder wall thickening, or pericholecystic fluid is identified. There is no intra or extra hepatic biliary ductal dilatation. The common duct measures approximately 4 mm in diameter. PANCREAS: The visualized head of the pancreas demonstrates normal echogenicity. The remaining pancreas is not visualized secondary to overlying bowel gas.SPLEEN: The spleen measures 8 cm in length.KIDNEYS: The right kidney measures 8.9 cm and the left kidney measures 10.3 cm in length. No evidence of hydronephrosis. There is a 1.2 x 1.4 cm left mid to lower pole renal cyst.ABDOMINAL AORTA: The proximal abdominal aorta measures 2.5 x 3.0 cm, the midportion measures 2.2 x 2.2 cm, and the distal abdominal aorta measures 2.3 x 2.2 cm.INFERIOR VENA CAVA: No significant abnormality noted.OTHER: The bladder is decompressed.
1. Increased hepatic parenchymal echogenicity consistent with hepatic steatosis with focal fatty sparing near the gallbladder fossa, appearing similar to the prior study.2. Left renal cyst.
