*Cases

Malignant Lymph Nodes - 2:36

Normal Cervical Lymph Nodes:
- Shape and Size: Usually oval with a smooth, well-defined border. Measure less than 1 cm
- Hypoechoic with echogenic central hilum
- Vascularity: On Doppler imaging, normal lymph nodes show minimal vascularity, often with a single hilar vascular signal.

Reactive Cervical Lymph Nodes:
- May enlarge but usually do not exceed 2-3 cm in diameter.
- Shape: They typically retain their oval shape with smooth borders, unlike the rounded shape often seen in malignant lymph nodes.
- Echotexture: They have a homogeneous appearance with a preserved echogenic hilum, indicating their benign nature.
- Vascularity: On Doppler ultrasound, reactive lymph nodes may show increased vascularity but it is usually centered at the hilum, which is a normal response to increased activity within the lymph node.

Malignant Cervical Lymph Node:
- Loss of central echogenic fatty hilum
- Enlarged
- Heterogeneous appearance
- Become rounded or irregular in shape
- Cystic necrosis: Ill-defined hypoechoic areas within lymph node
- Peripheral vascularity
