Multiple retroperitoneal cystic lymphangiomas in a pregnant woman: A case report

Cystic lymphangiomas are extremely rare benign vascular neoplasms generally found in childhood. Thought to arise from obstructed lymphatic channels during development, but may also arise secondary to trauma, inflammation, malignancy, and surgery or radiation exposure. They are usually seen in the head and neck or axillary region, and rarely in the abdominal cavity with only 1% occurring in the retroperitoneum. These are typically asymptomatic lesions incidentally identified by computer tomography, magnetic resonance imaging or ultrasound. Complete surgical resection with histologic confirmation of the diagnosis is the treatment of choice.We present a case of a 27-year-old woman with multiple cystic lymphangiomas in retroperitoneum, discovered incidentally by ultrasound during pregnancy.
