Male 66 years old with small cell neuroendocrine tumor metastatic to transplanted liver s/p partial hepatectomy July 2016. PET suggested possible new lesion. Evaluate on MRI. History: PET positive lesion ABDOMEN:LIVER, BILIARY TRACT: Status post resection of the right lobe of the transplant liver. At the posterior resection margin there is a 2.3 x 1.4 cm lesion which is T1 hypointense, mildly T2 hyperintense with restricted diffusion and enhancement. This corresponds to the FDG avid lesion seen on recent PET/CT. This lesion abuts the right adrenal gland which demonstrates nodular thickening. Although we don't see evidence of such, direct invasion into the right adrenal gland is not excluded.There is no biliary ductal dilatation. The hepatic vasculature appears patent.SPLEEN: No significant abnormality noted.PANCREAS: A 2.8 x 2.2 cm T1 hypointense, T2 hypointense lesion in the body of the pancreas unchanged since 2014 and may represent a small mucinous neoplasm. No pancreatic ductal dilatation.ADRENAL GLANDS: Nodular thickening of the right adrenal gland. The hepatic lesion abuts the right adrenal gland as described above. The left adrenal gland is unremarkable.KIDNEYS, URETERS: No hydronephrosis.RETROPERITONEUM, LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: Above average fecal burden.BONES, SOFT TISSUES: No significant abnormality noted.OTHER: Moderate right pleural effusion with associated compressive atelectasis. Trace left pleural fluid.
1.2.3 x 1.4 cm liver lesion at the posterior resection margin is highly suspicious for residual tumor2.A cystic lesion pancreatic body is stable since 2014, it may represent a mucinous neoplasm.
