History of melanoma. ABDOMEN:LIVER, BILIARY TRACT: Normal hepatic morphology and signal intensity. The previously described lesion within segment 7 has increased in size compared with 3/16/2016 MRI with reference measurements as below. The lesion demonstrates decreased T1 signal, increased T2 signal, peripheral rim enhancement, and mild internal heterogeneous enhancement with central necrosis. There is surrounding perfusion abnormality on arterial phase imaging which becomes isointense to liver parenchyma on portal venous and delayed imaging.No additional liver lesions. No biliary ductal dilatation. SPLEEN: No significant abnormality noted.PANCREAS: No significant abnormality noted.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: Bilateral simple appearing cysts.RETROPERITONEUM, LYMPH NODES: Enlarged right cardiophrenic lymph node, slightly increased in size from 3/16/2016 MRI.BOWEL, MESENTERY: No significant abnormality noted.BONES, SOFT TISSUES: No significant abnormality noted.OTHER: No significant abnormality noted.INDEX LESION MEASUREMENTS (Current exam date/time: 9/20/2016 12:45:00)RIGHT HEPATIC LESION: 3.4 x 2.6 cm (Image 69, Series 14); 1.8 x 1.6 cm on 3/16/2016 MRI.RIGHT CARDIOPHRENIC LYMPH NODE: 1.3 x 1.3 cm (Image 256, Series 14); 1.4 x 1.1 cm on 3/16/2016 MRI.
Hepatic segment 7 lesion and right cardiophrenic lymph node suspicious for metastatic disease, increased in size from 3/16/2016 MRI.
