title: Dropped omental fat post laparoscopy-assisted distal gastrectomy with omentectomy mistaken for malignant peritoneal seeding on sonography.
abstract: We report the sonographic findings in a case of dropped omental fat post laparoscopy-assisted distal gastrectomy with omentectomy for stomach cancer mistaken for malignant intraperitoneal seeding. Gray-scale sonography revealed an ovoid-shaped hyperechoic mass with central poorly defined hypoechoic portion in the right perihepatic space. Color Doppler sonography showed no blood flow within the mass. Contrast-enhanced CT scan of the liver revealed an oval-shaped fatty mass with a CT number of -100 HU
