ARTICLE HIGHLIGHTS
Research background
Paraduodenal pancreatitis (PP) is a relatively rare benign inflammatory pathology that can create differential diagnosis dilemmas with pancreatic cancer. Many articles deal with imaging findings in PP, but most of them are represented by case reports, short series, or reviews.
Research motivation
The aim of our work was to perform a systematic literature review of imaging findings in PP considering only original research articles with pathology and/or clinical-radiological follow-up as the reference standard.
Research objectives
To critically describe multimodality imaging findings in PP to help clinicians in the differential diagnosis with pancreatic cancer.
Research methods
Systematic review of original articles describing imaging findings in 8 or more patients affected by PP with pathological confirmation or clinical-radiological follow-up as the gold standard.
Research results
14 articles including 543 patients were included. Computed tomography, magnetic resonance imaging (MRI) and Endoscopic ultrasound (EUS) findings were described.
Research conclusions
PP has typical findings at imaging. MRI is the most accurate radiological imaging modality, but EUS has higher sensitivity in depicting duodenal wall alterations.
Research perspectives
Radiomics features extraction may be an option in order to further increase imaging accuracy in the differential diagnosis between PP and pancreatic cancer.
