@entity1 @entity3609 @entity5409 @entity101 @entity5 @entity293
@entity3609 are @entity5 developing as an anomaly of the lymphatic channels. Most of them are discovered in @entity1 and are located mostly in the head and neck with no differences between sexes. Retroperitoneal locations are rare, clinical symptoms not specific and are discovered incidentally. We report the case of a 32-year-old female sex @entity1 with a @entity5 situated in the retroperitoneum, behind the pancreas, discovered by abdominal ultrasound during a diagnostic work-out for @entity293 and @entity101 . Anamnesis, physical examination and CT-scan could not indicate the nature of the cyst. The @entity5 had a shape of a butterfly, crossing the midline in front of the aorta and vena cava. A laparotomy was indicated and established the diagnosis of a @entity5409 based on its macroscopic appearance. The @entity5 was approached from its right side by a generous Kocher maneuver and then from the left by disinsertion of the Treitz ligament and elevating the pancreatic body and splenic vessels. It was completely removed. Postoperative course was uneventful. Histopathologic examination confirmed the diagnosis of benign @entity3609 . At 2 years of follow-up the @entity1 was free of recidive. CONCLUSIONS: @entity3609 are rarely seen in adults. Precise diagnosis is made at laparotomy, imagistic test give details about walls, content, relationship with the surrounding structures and major blood vessels. Complete surgical resection represents the treatment of choice avoiding recurrence.
