Pancreatic Serous Cystadenoma with Compression of the Main Pancreatic Duct : An Unusual Entity

الملخص EN

Serous cystadenoma is a common benign neoplasm that can be managed without surgery in asymptomatic patients provided that the diagnosis is certain.

We describe a patient, whose pancreatic cyst exhibited a radiological appearance distinct from that of typical serous cystadenoma, resulting in diagnostic difficulties.

CT and MRI showed a 10 cm-polycystic tumor with upstream dilatation of the main pancreatic duct (MPD), suggestive of intraductal papillary mucinous tumor (IPMT).

Ultrasonographic aspect and EUS-guided fine-needle aspiration gave arguments for serous cystadenoma.

ERCP showed a communication between cysts and the dilated MPD, compatible with IPMT.

The patient underwent left pancreatectomy with splenectomy.

Pathological examination concluded in a serous cystadenoma, with only a ductal obstruction causing proximal dilatation.
