History of Crohn's disease with indeterminate liver mass seen on prior CT. MR for further evaluation. ABDOMEN:LIVER, BILIARY TRACT: The liver is normal in morphology. No focal hepatic lesion. At the site of the questionable left lobe lesion, there is no signal abnormality and this may have represented volume averaging on the prior CT. There is mild dilatation of multiple right intrahepatic bile ducts, but no obstructing lesion is evident. There is also a questionable filling defect in the distal common bile duct (series 701 image 22) which may represent a stone or debris. The gallbladder is unremarkable.SPLEEN: The spleen is upper limit of normal in size. There are multiple focal lesions in the spleen the largest of which measures 2.7 x 2.6 cm. These have increased T2 signal, do not restricted diffusion, and do not demonstrate enhancement on the postcontrast images. The smaller lesions appear to have thin internal septations or central dots.PANCREAS: Mild parenchymal atrophy. The main pancreatic duct is nondilated.ADRENAL GLANDS: 12 mm right adrenal nodule which demonstrates dropout on the out of phase images compatible with 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.OTHER: No significant abnormality noted.
1.No focal hepatic lesion at the site of clinical interest in the left hepatic lobe. Appearance on prior CT may have reflected volume averaging at the porta hepatis.2.Stable mild right intrahepatic ductal dilatation without obvious obstructing lesion. There is an apparent filling defect in the distal common bile duct which may represent debris or a small stone. This can be further evaluated with MRCP or ERCP as clinically warranted.3.Right adrenal adenoma.4.Multiple splenic lesions with benign imaging features, possibly cysts. These can be followed as clinically warranted.
