Clinical Presentation: Workup in a patient with malignant melanoma.Intravenous
pyelography showed no excretion of contrast on theright.
Comment: Splenic metastasis occur most commonly in malignantmelanoma,
lymphoma, and leukemia but can also occur in carcinoma ofthe ovary, breast, lung, and
stomach. Metastasis are usuallyhypoechoic and can be hyper or more commonly
hypovascular. Livermetastasis are frequent in malignant melanoma. These lesions areoften
hypervascular and can be extremely hemorrhagic.
Description: A large hypoechoic mass is seen in the spleen. CDFIreveals it to be
hypovascular and distorts the intrasplenic bloodvessels. This lesion is consistent with a
metastatic lesion.Urinary obstruction is present on the right with pelvo-caliceal anduretreal
dilatation secondary to a soft tissue lesion at thejunction of the ureter and baldder. This is
another secondarylesion of the malignant melanoma. Surprisingly, these lesions arenot
hypervascular on doppler nor on CT. Metastasis are also visiblein the liver.
