Can someone who actually understands this stuff please help me make sense of these results?
Abdominal MRI and MRCP were performed using standard multiplanar sequences, both native and dynamic post-contrast, for a patient who has already undergone surgery for bile duct cancer and resection of segments IVB and V of the liver, currently presenting with jaundice. The liver shows an atypical shape due to the previous resection. At the base of segment IV, there is a subcapsular lesion measuring 1.4 cm with diffusion restriction; it appears nearly isovascular and is likely secondary in nature. During the MRCP, dilation of the intrahepatic bile ducts was noted, reaching widths of up to 0.9 cm. There is also chronic narrowing of the common hepatic bile duct, which shows thickened walls near the confluence. At the confluence itself, there is an oval, inhomogeneous lesion measuring 2 cm with diffusion restriction; in certain sequences, it appears isovascular with the liver or slightly hypervascular. Morphologically, this could be considered a Klatskin tumor or a secondary lesion related to the primary disease. Post-cholecystectomy status. The splenoportal axis is patent, and the portal vein shows no signs of infiltration. The liver’s shape is atypical following the resection, specifically at the base of segment IV. In the gallbladder fossa, there remains an oval collection filled with hypointense content measuring 2 cm, which might just be an organized postoperative collection. Within the hepatogastric ligament, retroperitoneally, periportally, laterocavally, and in the mesentery, there are enlarged lymph nodes ranging from very small to borderline large at 1.1 cm. Above the head of the pancreas, there is an inhomogeneous lesion measuring 2.1 x 1.3 cm, and a similar one is located below the level of the stomach measuring 3.1 x 1.1 cm, both showing diffusion restriction. These infiltrates could be part of the primary disease or simply clusters of inhomogeneous lymph nodes. The spleen has homogeneous parenchymal intensity and normal size. A splenunculus measuring 1 cm is noted medially to the spleen. The pancreas is normally positioned and shaped, with no dilation of the pancreatic duct. The adrenal glands are normally positioned without signs of expansive processes. The kidneys are appropriately sized with preserved parenchyma and no signs of hydronephrosis. No free intraperitoneal fluid was detected on the scan.
