Useless and dangerous―fine needle aspiration of hepatic colorectal metastases

摘要

The potential benefit of FNAC in suspected liver lesions is the confirmation of suspected metastases, and this may be attained effectively by other investigations with less than 2% of benign lesions misdiagnosed as metastases. This benefit is outweighed by the risks, including the serious and often fatal complication of needle tract metastasis and the risk of deriving false reassurance from a false negative FNAC result.
