Subcentimeter retroperitoneal mesenteric lymph nodes refer to lymph nodes located in the retroperitoneal space that measure less than one centimeter in diameter. These nodes are part of the lymphatic system and play a crucial role in filtering lymph fluid and responding to infections or diseases. Their small size can sometimes make them difficult to detect in imaging studies, and their significance often depends on the clinical context, such as in cancer staging or monitoring. Enlarged lymph nodes in this area may indicate underlying health issues, such as malignancy or infection.

The group of lymph nodes in the small intestine is called the mesenteric lymph nodes. They are located in the mesentery, the tissue that attaches the small intestine to the back of the abdominal wall. Mesenteric lymph nodes play a crucial role in immune responses and help filter and trap pathogens and other harmful substances in the lymphatic system.
No, small sub-centimeter lymph nodes of the neck is not always considered abnormal. There are some lymph nodes located in the neck that are larger than others, and they do not have to have pathogens in them.
- transport lymph, clear, colorless fluid containing white blood cells - lymphocytes are manufactured in the lymph nodes - defence (Specific, Nonspecific) mechanism of the body - Return tissue fluid to the bloodstream - Transport fats from the digestive tract to the bloodstream
encephalitis (inflammation of the brain) and other infections of the central nervous system (CNS) gastroenteritis (inflammation of the stomach and intestines) acute mesenteric lymphadenitis (inflammation of lymph glands in the abdomen)
This typically means that there are a few very small lymph nodes (less than 1 cm in size) scattered throughout a specific area, such as the neck or abdomen. It could be a normal finding or could be indicative of a mild inflammatory response in the body. Further evaluation may be needed to determine the significance of these nodes.
The major lymph node sites in the body include the cervical (neck), axillary (armpit), inguinal (groin), and mesenteric (abdomen) regions. These nodes play a crucial role in filtering and trapping foreign particles or cancer cells from the lymphatic fluid before it returns to the bloodstream.
Typically referring to a measurement on an imaging study (xray, CT scan, MRI, ultrasound), "sub-centimeter" refers to a measurement less than 1 centimeter. For instance, a phrase such as "several sub-centimeter perihilar nodes are noted," means there are lymph nodes which are enlarged in the peri-hilar region of the lungs, but these are less than 1 centimeter in greatest diameter.
