Semiological characters and morphopathological-radiological correlations in duodenal malignancy

Area of Science:

• Gastroenterology
• Radiology
• Oncology

Background:

• Localized duodenal neoplasms are uncommon, often arising from adjacent duodeno-pancreatic malignancies.
• Accurate pre-operative characterization is crucial for effective patient management.

Purpose of the Study:

• To analyze the radiological semiology of localized duodenal tumors.
• To determine the role of radiological examinations in supporting anatomopathological diagnosis.

Main Methods:

• Retrospective analysis of 17 cases with localized duodenal tumors (9 vaterian ampullomas, 8 malignant duodenal tumors).
• All cases underwent computed tomography (CT) with multi-phase contrast enhancement and thin-section reconstructions.
• Two-thirds of cases also had conventional radiological examinations prior to CT.

Main Results:

• CT demonstrated characteristic imaging features for both vaterian ampullomas and other malignant duodenal tumors.
• Radiological findings showed potential correlations with morphopathological characteristics.
• Endoscopic evaluation and biliary stenting were performed pre-operatively in select cases.

Conclusions:

• Radiological examinations, particularly multi-phase CT, play a vital role in the pre-operative assessment of localized duodenal neoplasms.
• Imaging findings can aid in differentiating tumor types and guiding subsequent histopathological analysis.
