Summary
Ultrasound imaging effectively identifies abnormal cervical lymph nodes. Key indicators of abnormality include round shape, absent hilus, necrosis, calcification, and peripheral vascularity on sonography.
Area of Science:
- Medical Imaging
- Otolaryngology
- Radiology
Background:
- Cervical lymphadenopathy evaluation is crucial in clinical practice.
- Sonography is a primary imaging modality for assessing neck lymph nodes.
Purpose of the Study:
- To document common sonographic appearances of various causes of cervical lymphadenopathy.
- To differentiate normal from abnormal cervical lymph nodes using ultrasound.
Main Methods:
- Utilized gray-scale sonography.
- Employed color and power Doppler sonography.
- Documented sonographic features of diverse lymphadenopathy etiologies.
Main Results:
- Normal lymph nodes exhibit distinct sonographic features compared to abnormal ones.
- Abnormal nodes often present with a round shape and absent hilus.
- Features like necrosis, calcification, and peripheral vascularity indicate abnormality.
Conclusions:
- Sonography is a valuable tool for diagnosing cervical lymphadenopathy.
- Specific sonographic findings aid in distinguishing benign from malignant lymph nodes.
- Recognizing these features improves diagnostic accuracy in cervical lymph node assessment.
