Rare huge retroperitoneal cystic lymphangioma presenting as acute abdomen in an adult

Cystic lymphangiomas are rare benign tumors. Most are diagnosed in childhood and their presentation in adults is rare. Retroperitoneal cystic lymphangiomas constitute only 1% of lymphangiomas. Unfortunately the differentiation between cystic lymphangioma and other cystic tumors is often not possible and surgery with histology is essential for confirmation of diagnosis.A 20 year old lady with retroperitoneal cystic lymphangioma presented with acute abdomen. In the diagnosis of this patient, abdominal Ultrasound, Computerized Tomography (CT) and Magnetic Resonance Imaging (MRI) scans were obtained.
