The purpose of this essay is to help radiologists:
Review the main non-adenocarcinoma pancreatic lesions,
emphasizing an approach of key cross-sectional imaging features
Distinguish the different types ofneoplastic andnonneoplasticdisorders.
Discuss the management pancreatic lesions based on imaging pattern.
Pancreas imaging assessment usually demonstrates diseases with typical features.
Non-adenocarcinoma disorders show a wide spectrum of imaging features,
ranging from a tumor-like anatomic variant to malignant disease.
In this scenery,
imaging plays a crucial role in the diagnosis and management of pancreatic lesions.
We selected illustrative cases that were collected and classified didactically according to patterns type.
For each case,
we provide clinical and radiology presentations,
and teaching points.
We propose a classification of these cases as follows:
Serous cystic neoplasm...
Findings and procedure details
Serous cystic neoplasm
Case: Female patient (83 y.o.) asymptomatic (Fig. 1).
Serous cystadenomas (SCA) are a benign condition in women (75% x 25%,
Age: 6th-7th decades.
They are often diagnosed incidentally.
Slight predominance in the pancreatic head.
Composed of numerous small cysts (< 1 cm),
which are conjoined in a honeycomb-like pattern.
Tips⇒ fibrous portion may enhance after contrast injection (central scar) and central calcified areas may appear (stellate pattern).
CT:the appearance depends on the number of fibrous septa...
Pancreatic lesions have a broad spectrum of imaging findings and some of them may overlap.
the knowledge of relevant clinical informations and key imaging features are important to accurate characterization and differentiation of pancreatic lesions.
