Lymph nodes can be “swollen” (reactive) on imaging. Anything that causes inflammation can cause reactive lymph nodes. Most often this is from a transient viral infection; other less common causes include bacterial infection, malignancy, autoimmune disorders, as well as medications.Lymph nodes are small bean-shaped structures that are part of the body's immune system.
Lymph nodes are small bean-shaped structures that are part of the body's immune system. They 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. Adenopathy (also known as lymphadenopathy) refers to lymph nodes that have become enlarged or swollen due to an infection.
Cysts are fluid-filled sacs or pockets that can form in various parts of the body. Most cysts present little or no discomfort and are harmless. The majority disappear without treatment within a few months. Sometimes these cysts can rupture and release blood, known as hemorrhagic cysts.
A previous bone fracture that is now healed. No further follow-up or evaluation is needed for this finding.
Cancer cells can spread by breaking away from the primary (original) tumor, traveling through blood vessels or lymph nodes to reach other parts of the body. After traveling, cancer cells can attach to other tissues and grow more of the abnormal cells.
Neoplasm (also called tumors) refers to an abnormal mass of tissue that forms when cells grow and divide more than they should or do not die when they should. Neoplasms may be benign (not cancer) or malignant (cancer). Benign neoplasms may grow large but do not spread into, or invade, nearby tissues or other parts of the body. Malignant neoplasms can spread into, or invade, nearby tissues. They can also spread to other parts of the body through the blood and lymph systems.
