Mesentery, Retroperitoneum, and Spleen : Three Cases of Abdominal Cystic Lymphangiomas

Background: Abdominal cystic lymphangiomas (ACLs) are rare, benign malformations of lymphatic origin, typically presenting in children and seldom encountered in adults. Their nonspecific clinical features and broad differential diagnoses often lead to diagnostic delays. Case Presentations: We report three adult cases of ACLs with distinct anatomical locations—mesentery, retroperitoneal splenorenal space, and splenic parenchyma. All patients were symptomatic and underwent successful surgical excision. Histopathology confirmed cystic lymphangiomas in each case. Conclusion: These cases highlight the clinical polymorphism and anatomical diversity of ACLs. Imaging plays a crucial role in preoperative assessment, but surgical excision remains the cornerstone of treatment. Clinicians should maintain a high index of suspicion when evaluating abdominal cystic lesions, especially in unusual locations.
