78-year-old woman with history of cancer of unknown primary and multiple hepatic and splenic lesions. ABDOMEN:LIVER, BILIARY TRACT: A well-defined area of T2 hyperintensity is seen in the left lobe of the liver (series 4, image 20) represents a cyst. A hypoattenuating focus seen in segment 7 of the liver on the prior CT is not well seen on the current examination. A peripheral focus of arterial enhancement in the right lobe of the liver (series 14, image 22) is likely perfusional.The gallbladder is unremarkable.SPLEEN: Innumerable T2 hyperintense lesions are seen in the spleen, the largest of which near the splenic hilum (series 4, image 15) demonstrates progressive nodular enhancement with centripetal filling is and is most likely a hemangioma. The spleen is normal in size.PANCREAS: No significant abnormality noted.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: A septated cystic lesion in the right mid/upper pole is seen without definite enhancement and measures 27 x 22 mm (series 4, image 22). Multiple, additional subcentimeter cysts are seen in the right kidney. The left kidney appears normal.RETROPERITONEUM, LYMPH NODES: The enhancing paracaval focus seen on the prior CT is unchanged in size and measures 10 x 7 mm (series 4, image 29).BOWEL, MESENTERY: The visualized small bowel and colon appear normal.BONES, SOFT TISSUES: No significant abnormality noted.OTHER: No significant abnormality noted.
1.Innumerable splenic lesions, not compatible with sarcoidosis by imaging, largest focus demonstrates characteristics consistent with that of a hemangioma, smaller additional lesions more difficult to characterize due to size but may be followed up with imaging as clinically warranted.2.Bosniak 2F equivalent right renal cyst which may be followed up as clinically warranted.
