Learning objectives
Lesions of the pancreas encompass a heterogeneous group of processes which include benign and malignant entities.
The exhibit aims to illustrate a wide spectrum of US,
ERCP,
CT and MRI so that lesions can be morphologically differentiated.
Background
Pancreatic pathologies are encountered in the course of routine radiology practice due to escalating imaging volumes and greater diagnostic capabilities of contemporary imaging techniques or during routine pancreatic disease work up.
Accurate and timely imaging and diagnosis is essential to guide clinical management and help determine patient prognosis.
Lesions may require surgery,
follow up imaging or may be clinically insignificant and require no further action.
Advances in imaging techniques allow pancreatic lesions to be characterized on the basis of morphologic,
hemodynamic and metabolic findings which...
Imaging findings OR Procedure details
The exhibit will include a multimodality review pancreatic pathological processes and examples of each.
Congenital
A wide spectrum of anomalies of the pancreas and the pancreatic ductal system are commonly encountered at radiologic evaluation.
These anomalies may simulate various neoplastic,
inflammatory and posttraumatic conditions and should be part of the differential diagnosis for a variety of abnormalities found at diagnostic imaging.

Annular pancreas is a rare congenital anomaly in which incomplete rotation of the ventral anlage leads to a segment...
Conclusion
Solid lesions of the pancreas have a broad spectrum of neoplastic and non neoplastic causes.
A multimodality approach combines the strengths of individual imaging modalities and has a synergistic effect of improving diagnostic yield.
Key radiological features allow confident lesion characterization and differentiation from other disease entities.
