Complex lymphatic anomalies are unique diseases marked by abnormal lymphatic vessel development and growth. Imaging is crucial in the evaluation and management of complex lymphatic anomalies, with dynamic contrast-enhanced MR lymphangiography emerging as a valuable modality for visualizing abnormal lymphatic structures and informing treatment decisions. This article gives an overview of complex lymphatic anomalies and their management strategies, focusing specifically on generalized lymphatic anomaly, Gorham-Stout disease, Kaposiform lymphangiomatosis, and central conducting lymphatic anomalies.

Purpose: To assess the success rate of confirmation of ultrasound-guided intranodal needle positioning by saline injection for dynamic contrast-enhanced magnetic resonance lymphangiography (DCMRL) in pediatric patients.
Material And Methods: Data from children undergoing nodal DCMRL after ultrasound-guided needle positioning into inguinal lymph nodes and validation of the needle position by injection of plain saline solution between 05/2020 and 12/2022 were reviewed. On injection of saline solution, adequate needle position was confirmed by lymph node distension without leakage.

Dynamic contrast-enhanced magnetic resonance lymphangiography is a high-resolution imaging technique that has emerged as the preferred method for evaluating lymphatic anatomy and flow dynamics due to its precise anatomical detail. The lymphatic system has a complex anatomical distribution, and variability is common among individuals with cardiac abnormalities, particularly congenital heart disease. Lymphatic imaging has recently been revolutionized by the introduction of MR lymphangiography.

Lymphatic leakage, manifesting as chylothorax or chylous ascites, arises from traumatic or nontraumatic causes and poses severe risks such as malnutrition and increased infection susceptibility. Accurate diagnosis and an effective treatment strategy necessitate comprehensive lymphatic imaging. Conventional lymphangiography and dynamic contrast-enhanced MR lymphangiography (DCMRL) have been widely used and studied as effective lymphatic imaging methods.

Article Synopsis
- The study evaluates the effectiveness of dynamic contrast-enhanced magnetic resonance lymphangiography (DCMRL) in diagnosing and planning treatment for different lymphatic disorders.
- A retrospective analysis included 70 patients, primarily with traumatic chylothorax and lymphatic leaks, assessing DCMRL's technical success and its influence on clinical outcomes.
- Results showed high technical success rates for nontraumatic disorders, with 90.3% of patients with suitable anatomy achieving clinical improvement, highlighting DCMRL's role in identifying underlying causes and planning interventions.
