Özet

Learning objectives

To define and illustrate infective, inflammatory pathologies of second segment of duodenum, benign and malignant lesions arising from the duodenum and to make differential diagnosis.

Background

The duodenum is the first C-shaped section of the small intestine and is the continuation of the pyloric segment of the stomach (Figure 1). It is important to recognize lesions of the duodenum because of its close relationship with surrounding anatomical structures such as pancreas, gallbladder, colon, and kidney and because it may present with many different pathologies.

Findings and procedure details

CT is most used to identify duodenal lesions, but sometimes MRI, MRCP and even ultrasound findings contribute differential diagnosis.DUODENAL DIVERTICULUMDuodenal diverticulum (DD) is less frequently seen than colonic diverticula (Figure 2). CT appearance of a DD includes a saccular outpouching, which may resemble a mass-like structure interposed between the duodenum and the pancreas that contains air, an air-fluid level, fluid, contrast material, or debris (1). DD usually arises from the second part of the duodenum and may present as true or congenital diverticula involving all...

Conclusion

It is important for radiologists to define duodenal lesions and understand the basic features used in differential diagnosis, both to speed up the diagnosis and treatment process and to avoid unnecessary and multiple radiologic examinations.
