Reason: 34 yo female with hx of gallbladder polyp; please evaluate for abnormalities. ABDOMEN:LIVER, BILIARY TRACT: The liver demonstrates normal background parenchymal signal intensity and enhancement. There are a couple small cysts within segment 6/7. No suspicious focal hepatic lesions are identified. The hepatic vasculature appears patent.The gallbladder is normally distended and lacks diffuse wall thickening. There is a filling defect within the gallbladder along the body wall with reference measurements below which demonstrates enhancement and is compatible with a polyp. Otherwise, there is equivocal irregular focal thickening of the gallbladder wall at the fundus (series 7, image 26) which is nonspecific but could reflect adenomyomatosis and/or small polyps.The biliary system is nondilated. There is mild apparent focal narrowing of the common hepatic duct just proximal to the confluence which is favored to reflect artifact from crossing vessel given lack of upstream dilatation.SPLEEN: No significant abnormality noted.PANCREAS: The pancreas demonstrates normal parenchymal signal intensity and enhancement without focal lesions identified. The pancreatic duct is nondilated.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: Subcentimeter left renal cyst.RETROPERITONEUM, LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: No significant abnormality noted.BONES, SOFT TISSUES: No significant abnormality noted.OTHER: No significant abnormality noted.INDEX LESION MEASUREMENTS (Current exam date/time: 9/19/2016 08:00:00)GALLBLADDER FILLING DEFECT: 0.9 x 1.0 cm (Image 60, Series 10).
1.10 mm enhancing gallbladder polyp differential considerations for which include adenomatous polyp and adenocarcinoma; surgical consultation is recommended. No evidence of extramural invasion.2.Additional focal thickening of the gallbladder wall fundus may reflect adenomyomatosis or additional small polyps.
