RIGHT LYMPHATIC DUCT AND CISTERNA CHYLI

Drains lymph from body’s right upper quadrant and right side of the head, neck, thorax and the right upper limb
Course At the root of the neck, it enters the
junction of the right internal jugular and right subclavian veins, the right venous angle

If present, is about 0.5 in. (1.3 cm) long
Fate Opens into the beginning of the right
brachiocephalic vein
Alternatively, the trunks open independently into the great veins at the root of the neck

Cisterna Chyli

An enlarged lymphatic vessel About 6 centimeters long Located in the lumbar region of the
abdominal cavity, just to the right of the abdominal aorta
Receives and temporarily stores lymph as it travels upward from the lower portion of the body.
Cisterna Chyli
![Page 9: Right Lymphatic Duct and Cisterna Chyli](https://reader036.vdocuments.us/reader036/viewer/2022062417/55279f434979595f178b4862/html5/thumbnails/9.jpg)
The lymphatic trunks draining the lower half of the body merge in the abdomen
Sometimes forming a dilated sac, the cisterna chyli
From this sac, the thoracic duct ascends into and then through thorax to enter the left venous angle

Cisterna Chyli can mimic the appearance of an enlarged retrocrural (a triangular region within the mediastinum, middle section of chest cavity) lymph node
Proper identification depends on its characteristic location, tubular configuration, attenuation (less harmful) closer to that of water than soft tissue, and lack of substantial change in size despite changes in disease at other sites
