Mucinous cystadenomas (MCN) of the pancreas are a type of mucinous cystic neoplasm of the pancreas.

It is a large uni/multilocular cystic pancreatic neoplasm lined by columnar mucinous epithelium. While mucinous cystadenomas very infrequently communicate with the pancreatic duct ¹³, they can cause partial pancreatic ductal obstruction ¹¹. They are considered premalignant or malignant lesions with usually elevated CEA and CA 19-9 serum levels.

Location

Largely (~80%) occur in the body or tail of the pancreas, and less commonly in the head of the pancreas (~20%) ¹¹.

Radiographic features

CT

the tumor contour tends to be rounded or ovoid although this is not an absolutely specific feature ²
associated calcification when present tends to be more peripheral ^1,11
contents of the lesion may be heterogenous in attenuation ²
internal septations may be present and tend to be linear or curvilinear ²

Differential diagnosis

On ultrasound or CT consider:

mucinous cystadenocarcinoma of the pancreas: at times almost impossible to differentiate on ultrasound or CT from a mucinous cystadenoma ⁸
pancreatic pseudocyst
oligocystic variant of serous cystadenoma of the pancreas
pancreatic hydatid cyst ¹⁴
