Abnormal axillary lymph nodes in rheumatoid arthritis

Area of Science:

• Radiology
• Rheumatology
• Oncology

Background:

• Arthritis, especially rheumatoid arthritis, can affect various body systems.
• Axillary lymph node assessment is crucial in evaluating inflammatory and neoplastic conditions.

Purpose of the Study:

• To evaluate the characteristics of axillary lymph nodes in patients with arthritis using mammary radiography.
• To identify imaging features indicative of abnormality in these lymph nodes.

Main Methods:

• Retrospective analysis of mammary radiography images.
• Inclusion of 56 patients diagnosed with arthritis, primarily rheumatoid arthritis.
• Detailed assessment of axillary lymph node morphology and attenuation.

Main Results:

• Abnormal axillary lymph nodes were identified in 32 out of 56 patients (24 definite, 8 probable).
• Key features of abnormal nodes included increased attenuation and a rounded morphology.
• Absence of normal fatty replacement was a consistent characteristic of abnormal nodes.

Conclusions:

• Mammary radiography can detect abnormalities in axillary lymph nodes in patients with arthritis.
• Specific imaging findings (increased attenuation, rounded shape, lack of fat) suggest lymph node involvement.
• Further investigation may be warranted for patients with these radiographic findings.
