paraaortai

Paraaortai refers to lymph nodes located near the aorta, a major artery in the body. These lymph nodes are part of the lymphatic system, which plays a crucial role in the immune response and fluid balance. They are situated in the abdominal cavity, surrounding the aorta. Their primary function is to filter lymph fluid, trapping foreign substances like bacteria, viruses, and abnormal cells, and to house immune cells that fight infection and disease. Enlargement or inflammation of paraaortic lymph nodes can be indicative of various medical conditions, including infections, inflammatory processes, or malignancy, such as lymphoma or metastatic cancer. Medical imaging techniques like CT scans or MRIs are often used to visualize and assess these lymph nodes. When suspected of harboring disease, a biopsy may be performed to obtain a tissue sample for definitive diagnosis. Treatment for issues related to paraaortic lymph nodes depends entirely on the underlying cause.
