Chapter 357 Cystic Diseases of the Biliary Tract and Liver
Cystic lesions of liver may be initially recognized during infancy and childhood (see Table 357-1 on the Nelson Textbook of Pediatrics website at www.expertconsult.com). Hepatic fibrosis can also occur as part of an underlying developmental defect (see Table 357-2 on the Nelson Textbook of Pediatrics website at www.expertconsult.com). Cystic renal disease is usually associated and often determines the clinical presentation and prognosis. Virtually all proteins encoded by genes mutated in combined cystic diseases of the liver and kidney are at least partially localized to primary cilia in renal tubular cells and cholangiocytes.
