Female; 57 years old. Reason: to rule out hcc per protocol ABDOMEN:LIVER, BILIARY TRACT: 1.3 x 1 cm well-circumscribed mildly T2 hyperintense lesion in segment 4A with homogeneous arterial enhancement and no washout on delayed images, most likely reflecting a hemangioma though the appearance is somewhat atypical given the relatively mild T2 hyperintensity and early diffuse arterial enhancement/'flash filling' appearance given the size of the lesion. The lesion does not meet the criteria for hepatocellular carcinoma. No additional focal hepatic lesion. No biliary ductal dilation.SPLEEN: No significant abnormality noted.PANCREAS: No significant abnormality noted.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: No significant abnormality noted.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.
Segment 4A lesion, most likely benign and a hemangioma, given early arterial enhancement with persistent contrast retention noted on subsequent delayed phase imaging. While a hepatic adenoma is another differential consideration, the homogeneous pattern of enhancement again would favor a hemangioma. The lesion does not meet the criteria for hepatocellular carcinoma. No additional focal hepatic lesion.
