History of osteomyelofibrosis. Evaluate splenic size. ABDOMEN:LIVER, BILIARY TRACT: Hepatomegaly measuring 19.3 cm in craniocaudal dimension. It is markedly decreased in T2-weighted signal intensity compatible with iron deposition. No intra or extrahepatic biliary ductal dilatation. No focal suspicious lesion is apparent.SPLEEN: Significant splenomegaly measuring 17.8 cm in craniocaudal dimension and up to 13.9 x 6.8 cm in the axial plane. The spleen is diffusely hypointense on T2-weighted imaging. Stable punctate T2 hyperintense foci are noted in the spleen. Multiple presumed siderotic nodules.PANCREAS: Unchanged punctate cystic focus in the pancreatic head may represent a sidebranch IPMN without suspicious imaging features. No pancreatic ductal dilatation.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: No significant abnormality noted.RETROPERITONEUM, LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: Very low marrow signal intensityBONES, SOFT TISSUES: No significant abnormality noted.OTHER: No significant abnormality noted.
1.Hepatosplenomegaly as described above. Significant iron deposition of the liver and spleen.2.Marrow signal abnormality compatible with history of myelofibrosis.
