PATHOLOGY

Detailed explanation-1: -A small bean-shaped structure that is part of the body’s immune system. Lymph nodes filter substances that travel through the lymphatic fluid, and they contain lymphocytes (white blood cells) that help the body fight infection and disease. There are hundreds of lymph nodes found throughout the body.

Detailed explanation-2: -A normal lymph node is ovoid in shape, hypoechoic to the adjacent muscle and frequently contains an echogenic fatty hilum (Fig. 1a). The hilum is a linear, echogenic, non-shadowing structure that contains the nodal vessels and it appears continuous with the fat around the node.

Detailed explanation-3: -Lymph nodes are located in many parts of the body, including the neck, armpit, chest, abdomen (belly), and groin. They contain immune cells that can help fight infection by attacking and destroying germs that are carried in through the lymph fluid. There are hundreds of lymph nodes throughout the body.
