[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.

Biopsy. A biopsy is a surgical procedure in which a small amount of tumor tissue is removed and sent to a lab for evaluation. The purpose of a biopsy is to establish a diagnosis in a patient who has a tumor. A biopsy can be performed as part of the surgery to remove a tumor, or as a separate procedure.In either case, the surgeon removes a small amount of tumor tissue and sends it to a lab for a pathologist to review.Three types of biopsy are often performed in patients with brain tumors:1  Needle Biopsy: A small cut is made and a small hole, called a burr hole, is drilled in the skull.n either case, the surgeon removes a small amount of tumor tissue and sends it to a lab for a pathologist to review.
