Abstract
|
|
|
|
Intraductal papillary mucinous neoplasm (IPMN) is known to arise from intraductal proliferation of mucinous cells with findings of marked dilatation of the biliary or pancreatic duct. There are reports of the metastasis and extension of pancreatic IPMN. However, cases of biliary IPMN with direct metastasis, or metastasis to distant locations, are rare. We present a case of metastasis of biliary IPMN with unexpected direct extension into the thoracic cavity, and we attempt to account for the mechanism of this extension.
