Macrocystic serous cystadenoma of the pancreas, about a case

Serous cystadenomas of pancreas are unusual cystic tumour. The microcystic forms is more common and its radiological diagnosis is easy. However, the macrocystic unilocular form of serous cystadenoma can be mistaken with other malignant macrocystic lesions of the pancreas. We report the case of a 17 year-old girl, admitted to the National Hospital of Niamey (Niger), with abdominal pain and an unilocular macrocystic serous cystadenoma of pancreas, diagnosed after histological examination of the surgical specimen. The diagnostic tests, including ultrasound, CT scan, MRI, endoscopic ultrasonography are inconclusive. Challenge of its management is related to the preoperative diagnosis.
