A granuloma (a non-cancerous lesion that contains small abnormal clumps of cells) forms as a result of an inflammatory reaction in body tissues. Granulomas that are found in the liver are associated with inflammation caused by infection (e.g. mycobacterial infection), liver disorders (e.g. primary biliary cholangitis), and noninfectious causes (e.g. sarcoidosis, medication-induced liver injury).
Liver metastases are lesions seen in the liver caused by the spread of cancer from other organs to the liver.
The intrahepatic biliary duct is a tube that is inside the liver and transports bile in the liver. Dilatation is the expansion or widening of the duct. Dilatation of the bile duct can be due to several causes including obstruction (blockage) of the bile duct, presence of a cyst or mass in the bile duct, benign (non-cancerous) strictures or infection. Symptoms, if present, could include right upper quadrant pain and/or jaundice.
A cyst is a pocket of fluid which usually causes no signs or symptoms and needs no treatment. Subhepatic cysts are situated or occurring under the liver.
A liver lesion is an abnormality seen on a liver-imaging test A liver lesion may involve small to large areas of your liver, and the severity of the underlying condition may range from relatively minor to life-threatening. These lesions will need further work up to for a diagnosis.
A splenic lesion is an abnormality seen on a spleen-imaging test. A spleen lesion may involve small to large areas of your spleen, and the severity of the underlying condition may range from relatively minor to life-threatening. These lesions will need further work up to for a diagnosis.
