[Echography of the superficial lymph nodes]

Area of Science:

• Radiology and Medical Imaging
• Oncology
• Pathology

Background:

• Superficial lymph nodes are crucial indicators of various pathologies, including infections, inflammation, and malignancies.
• Accurate imaging of these nodes is essential for diagnosis, staging, and treatment monitoring.
• Echography (ultrasound) offers a non-invasive method for evaluating superficial lymph node regions.

Purpose of the Study:

• To review the existing literature on the echographic examination of diseased superficial lymph nodes.
• To discuss the anatomy, examination techniques, and diagnostic capabilities of echography for lymph nodes.
• To compare echography with computed tomography (CT) and magnetic resonance imaging (MRI) in lymph node assessment.

Main Methods:

• Comprehensive literature review of studies focusing on echographic examination of superficial lymph nodes.
• Analysis of anatomical considerations and standardized echographic techniques for cervical, axillary, internal mammary, and inguinal regions.
• Evaluation of the role and limitations of CT and MRI in conjunction with echography.

Main Results:

• Echography effectively differentiates between normal, inflammatory, and tumoral lymph nodes based on characteristic features.
• Specific echographic presentations are discussed for various pathological conditions.
• Indications for echography are highlighted in the context of ear-nose-throat cancers, breast cancer, and lymphomas.

Conclusions:

• Echography is a valuable tool for the initial assessment of superficial lymph nodes.
• It plays a significant role in the diagnostic workup of suspected malignancies and inflammatory conditions affecting lymph nodes.
• Understanding echographic findings aids in clinical decision-making for further investigations and management.
