Intraabdominal Lymphatic Malformations: Pearls and Pitfalls of Diagnosis and Differential Diagnoses in Pediatric Patients

Abstract

Lymphatic malformations (LMs) are among the most common pediatric lesions. Due to their rarity, tendency to present later in life than their superficial counterparts, and often incidental identification, intra-abdominal LMs pose a diagnostic dilemma and more prevalent pathologies must be first carefully excluded. Although the diagnosis of the majority of intra-abdominal LMs can be reliably made based on clear understanding of characteristic imaging findings, histologic correlation may be necessary in some cases.
