ductal dilation

Ductal dilation refers to the enlargement or widening of a duct, which is a tube that transports fluids within the body. This can happen in various organs, such as the milk ducts in breasts or bile ducts in the liver. When a duct becomes dilated, it may indicate an underlying issue like blockage, inflammation, or narrowing elsewhere that causes fluid to back up. Ductal dilation can be detected through imaging tests and may require further investigation to determine the cause and appropriate treatment. It’s often a sign that something is affecting the normal flow within the duct.
