lymphadenopathy
Pronunciation: lim-fad-uh-NOP-uh-thee
Abnormal enlargement of lymph nodes, often evaluated in oncologic imaging for staging and treatment response assessment.
Full Definition
Lymphadenopathy refers to the abnormal enlargement of lymph nodes, which can be detected and characterized through various imaging modalities. In oncologic radiology, lymphadenopathy assessment is fundamental for cancer staging, treatment planning, and monitoring therapeutic response. Enlarged lymph nodes are typically defined by specific size criteria that vary by anatomical location, such as greater than 10mm in short-axis diameter for most nodal stations. The morphological characteristics of enlarged nodes, including shape, enhancement patterns, and internal architecture, provide important diagnostic information. Lymphadenopathy may represent malignant involvement, reactive changes, or inflammatory processes, requiring careful correlation with clinical presentation and other imaging findings.
Usage
Usage note: Specify anatomical location and measurement criteria when describing lymphadenopathy.
