Female 65 years old Reason: liver lesion History: as above LUNG BASES: Bibasal atelectasis.ABDOMEN:LIVER, BILIARY TRACT: There is signal dropout within the liver suggestive of hepatic steatosis.There is a 3.1 x 2.4 cm lobulated T1 hyperintense/T2 hypointense lesion within segment 7 which has thin enhancing internal septations and minimal mural nodularity in the lateral wall. The central T1 hyperintense signal likely reflects proteinaceous material/hemorrhage.A nonenhancing T2 hyperintense lesion measuring 1.7 cm in the left hepatic lobe has the appearance of a simple cyst.Multiple additional T2 hyperintense lesions are too small to characterize.SPLEEN: Mild splenomegaly measuring 13.3 cm.PANCREAS: A 1.3 x 1.2 cm lesion projects off the dorsal aspect of the pancreatic body (series 801, image 25). This follows pancreatic parenchymal signal on all sequences and although the location is somewhat atypical this likely represents contour irregularity. Immediately medial to this there is a 0.7 cm, T2 hyperintense lesion, likely representing a side branch IPMN (series 801, image 25).ADRENAL GLANDS: A 2.7-cm nodule arising from the left adrenal gland demonstrates signal dropout on out of phase images and is suggestive of an adenoma.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.
1. Lobulated, 3.1 cm, T1 hyperintense lesion within segment 7 with thin enhancing internal septations and small enhancing mural nodule. This is most compatible with a biliary cystadenoma. Biliary hamartoma or complex hepatic cyst could have a similar appearance. 2. Probable contour irregularity of the dorsal aspect of the pancreatic body. Given the somewhat atypical location follow up MRI is recommended to ensure stability.3. subcentimeter IPMN adjacent to above-described lesion.4. Left adrenal adenoma.
