A liver hemangioma is a noncancerous (benign) mass in the liver. Liver masses or lesions are usually detected on CT scans, and their visibility on these scans depends on the weakening difference between the lesion and the normal liver. These pathologies are characterised by an autoimmune reaction mediated by T-helper lymphocytes that targets the ducts of exocrine glands in Sjgren's syndrome and glandular parenchyma in immunoglobulin G4-related diseases. In many cases, there is more then one tiny bright spot, and they are of differing sizes. 1996 Sep;80(3 Pt 1):225-35. doi: 10.1006/clin.1996.0118.
