Retroperitoneal lymphatic malformation is a rare benign vascular malformation, of various locations, which can reveal itself at any age in its abdominal localizations. The retroperitoneal localization of this malformation is extremely rare. The clinical symptomatology is polymorphic depending on the lesion volume and the presence or absence of complications. The diagnosis is evoked by the liquid character of the retroperitoneal mass on ultrasound, CT scan and abdomino-pelvic MRI, brought during surgery and confirmed by the histological study of the surgical specimen. The treatment of choice is complete surgical removal of the mass.
