Abstract

Objective: Describe the number and characteristics of Inguinal Lymph nodes in patients with Chyle Leakge who were made intranodal Lymphatic Magnetic Resonance Imaging (MRI) by ultrasound. Materials and Methods: Cross-sectional descriptive study, 35 patients with Chyle Leakge who were made intranodal Lymphatic Magnetic Resonance Imaging (MRI) at the Center of Diagnostic Imaging and Interventional Radiology, Hanoi Medical University Hospital from December 2023 to December 2024. Results: 35 patients (21 males, 14 females; mean age 49.63 ± 18.85 years). The majority of patients in the study were male (60%). There was no statistically significant difference in the number of lymph nodes between age groups and genders (p > 0.05). The mean short-axis diameter of the left inguinal lymph nodes was 5.24 ± 1.47 mm, and the right side was 5.35 ± 1.47 mm. The long-to-short axis ratio > 1 in all patients, indicating a typical oval shape. Most lymph nodes had preserved sinuses with clear boundaries between the cortex and the sinus. However, a small proportion (2.86% - 5.72%) showed irregularly thickened cortex or irregular nodal borders, suggesting a higher risk of node rupture, contras leakage, or poor quality lymphatic imaging. Conclusions: The number of inguinal lymph nodes on both sides showed no statistically significant difference by gender and age. Most patients with chyle leakage have normal bilateral lymph nodes on ultrasound. Ultrasound evaluation of inguinal lymph nodes should be performed before doing lymphatic MRI to select appropriate nodes and reduce complications during imaging.
