Female 62 years old known hepatic abscess, status post 3 courses of antibiotics. Also potential IPMN. Please eval for resolution of abscess and confirmation of IPMN. ABDOMEN:LIVER, BILIARY TRACT: There is mild wedge shaped signal abnormality including restricted diffusion, T2 hyperintensity and heterogeneous enhancement but no washout in segment 7 in the region of the previously seen hepatic abscess. There are linear regions of nonenhancement corresponding to hypoattenuating regions seen on the prior CT. The region of signal abnormality is not discretely measurable but has improved since the CT from 9/24/2016. A focus of restricted diffusion in region segment 6 (series 12, image 81) is associated with susceptibility artifact but no enhancement in the location of the hepatic/perihepatic abscess seen on CT from 8/19/2016. Scattered punctate foci of T2 hyperintensity are too small to accurately characterize but appear to represent simple cyst giving the degree of T2 hyperintensity. No cholelithiasis, biliary ductal dilatation or ascites.SPLEEN: No significant abnormality noted.PANCREAS: There is a 9 x 7 mm T2 hyperintense lesion in the body of the pancreas with no clear communication with the main pancreatic duct and no enhancement. A second lesion with similar imaging characteristics measures 4 x 3 mm. There is no pancreatic ductal dilatation. The pancreas enhances homogeneously.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: No significant abnormality noted.RETROPERITONEUM, LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: Colonic diverticulosis.BONES, SOFT TISSUES: No significant abnormality noted.OTHER: No significant abnormality noted.
1.Mild signal abnormality and heterogeneous enhancement within hepatic segment 7 has improved since the prior CT and is compatible with the history of hepatic abscess.2.The smaller hepatic/perihepatic abscess in region of segment 6 has resolved3.Two cystic lesions within the pancreatic body are favored to represent side branch IPMNs.
