title: [Mediastinal pseudocyst in hereditary pancreatitis].
abstract: A 6 year-old child was hospitalized for thoracoabdominal pain. There was a clinical and radiological right pleural effusion. Ultrasonography showed a pseudocyst of the head of the pancreas. CAT scan and operative opacification showed a mediastinal extension of the pseudocyst, with no communication with the pleural effusion. This pseudocyst illustrates an unusual variation of a known complication of this disease. Recovery was obtained via fistulization into the jejunum.
