Retroperitoneal cysts: a case report.

Retroperitoneal cysts are rare lesions, variable from asymptomatic cases with incidental discovery to case with acute or chronic abdominal discomfort. A 50-year-old female after a car crash refered chronic abdominal pain. An X-ray revealed the presence of sternal and multiple costal fractures. Abdominal ultrasonography (US) and computed tomography (CT) lead to the discovery of a retroperitoneal cyst too. As the patient was well after fractures solution, we decided to control the cyst in the time. In symptomatic cases surgery is the treatment of choice. The advent of laparoscopic surgery allows resection of these cysts to be achieved without full laparotomy.
