51-year-old man with a history of metastatic melanoma Axial precontrast 3D SPGR images (Figure 17.25.1) reveal multiple T1 hyperintense lesions throughout the liver, representing melanoma metastases. Note also geographic decreased signal intensity in the left hepatic lobe, likely representing fibrotic changes from previous radiotherapy. Many of the lesions are more difficult to visualize on equilibrium phase images obtained 20 minutes after gadoxetate disodium (Eovist) administration (...

A case of metastatic melanoma of the antrum and duodenal bulb is reported with rare endoscopic findings. A 59-year-old male patient was presented with nausea, vomiting, and abdominal pain one year after excision of malignant melanoma from the back. The tumor was classified as Clark IV, Breslow III. Upper gastrointestinal endoscopy revealed one melanotic polypoid mass with ulcerations at the tip in the antrum and two in the duodenal bulb. Endoscopic biopsy of these polypoid masses showed malignant melanoma metastases. Patients with gastrointestinal symptoms and a history of melanoma should be investigated for the presence of gastrointestinal metastases even if the original primary malignancy was diagnosed years prior to the patient presentation.

55-year-old woman with chronic liver disease Axial fat-suppressed FSE T2-weighted images (Figure 2.23.1) demonstrate a cirrhotic liver with diffuse, innumerable, small low-signal-intensity nodules. Axial arterial, portal venous, and hepatobiliary phase postgadolinium (Eovist) 3D SPGR images (Figure 2.23.2) demonstrate heterogeneous enhancement of the background parenchyma, particularly in the right hepatic lobe. The multiple nodules are initially hypointense on arterial and portal venous phase images but become hyperintense relative to adjacent liver on the hepatobiliary phase image....
