muzinöses Zystadenom des Pankreas
Mucinous cystadenomas (MCN) of the pancreas are a type of mucinous cystic neoplasm of the pancreas.
Previously believed to occur exclusively in middle age females , it has occasionally been described in males .
It is a large uni/multilocular cystic pancreatic neoplasm lined by columnar mucinous epithelium. While mucinous cystadenomas very infrequently communicate with the pancreatic duct , they can cause partial pancreatic ductal obstruction . They are considered premalignant or malignant lesions with usually elevated CEA and CA 19-9 serum levels.
Largely (~80%) occur in the body or tail of the pancreas, and less commonly in the head of the pancreas (~20%) .
- the tumor contour tends to be rounded or ovoid although this is not an absolutely specific feature
- associated calcification when present tends to be more peripheral
- contents of the lesion may be heterogenous in attenuation
- internal septations may be present and tend to be linear or curvilinear
On ultrasound or CT consider:
- mucinous cystadenocarcinoma of the pancreas: at times almost impossible to differentiate on ultrasound or CT from a mucinous cystadenoma
- pancreatic pseudocyst
- oligocystic variant of serous cystadenoma of the pancreas
- pancreatic hydatid cyst
