Several theories have been proposed to explain the development of ectopic liver at different sites: development of an accessory lobe of the liver with atrophy or regression of the original connection to the main liver, (4) migration or displacement of a portion of the cranial part (Pars hepatica) of the liver bud to other sites, (6) dorsal budding of hepatic tissue before the closing of the pleuroperitoneal canal (may explain how EL develops in the thoracic cavity such as esophagus, pericardium, intra pleural or extra pleural), (7) trapping of hepatocyte-destined mesenchyma in different areas (8) and entrapment of nests of cells in the region of the foregut following closure of the diaphragm or umbilical ring.
1,3] The reasons postulated for these observations are the earlier closure of the pleuroperitoneal canal on the right side than on the left, and the protective effect of the liver on the right diaphragm.
It is more common on the left side as the right pleuroperitoneal canal closes earlier than the left (4).
