[edit on Wikidata] A chylothorax (or chyle leak) is a type of pleural effusion. It results from lymph formed in the digestive system called chyle accumulating in the pleural cavity due to either disruption or obstruction of the thoracic duct. In people on a normal diet, this effusion can be identified by its turbid, milky white appearance, since chyle contains high levels of triglycerides.
A biopsy is a medical test commonly performed by a surgeon, interventional radiologist, or an interventional cardiologist involving sampling of cells or tissues for examination.It is the medical removal of tissue from a living subject to determine the presence or extent of a disease.he tissue is generally examined under a microscope by a pathologist, and can also be analyzed chemically. When an entire lump or suspicious area is removed, the procedure is called an excisional biopsy.
Here are some types of biopsies: Needle biopsy. Most biopsies are needle biopsies, meaning a needle is used to access the suspicious tissue. CT-guided biopsy. A person rests in a CT-scanner; the scanner's images help doctors determine the exact position of the needle in the targeted tissue.
