Inguinal and Axillary LN Size Distribution

Completed

• Conditions: Lymph Nodes
• Interventions: Diagnostic Test: chest and abdominoplevic CT

• Registration Number: NCT06559202
• Lead Sponsor: Gachon University Gil Medical Center

Brief Summary

Recently, intralymphatic allergen-specific immunotherapy (ILIT) showed promising treatment outcomes for allergic rhinoconjunctivitis. However, the normal size distribution of superficial lymph nodes (LNs) on the trunk that are potential target LNs for ILIT has not been evaluated.

The objective of this study is to investigate the distribution of LN size in inguinal and axillary area.

Detailed Description

In this study, the long-axis diameters of the largest LNs in the inguinal and axillary areas were retrospectively measured in subjects who underwent chest and abdominopelvic computed tomography on the same day for health screening purposes from September 2022 to November 2022.
