[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.
Ultrasound-and MRI-guided prostate biopsies are performed to collect tissue samples from the prostate gland for examination by a pathologist to determine whether or not the tissue is cancerous. Biopsies are most commonly performed under ultrasound guidance.During the procedure, a special biopsy needle is inserted into the prostate gland through the wall of the rectum to remove several small samples of tissue for pathologic analysis. This method is known as transrectal ultrasound (TRUS) guided biopsy.he MRI-guided biopsy can be performed with an endorectal approach or a transperineal approach. For the endorectal biopsy, the patient is usually lying on his stomach. The biopsy device has a built in endorectal coil to aid in visualization and a guidance slot for biopsy needle insertion.
