Duodenal pseudotumour: a silent impacted common bile duct calculus

The disappearing abdominal mass: a duodenal pseudotumour

Reports of inflammatory pseudotumours can be found in the literature affecting different organs of the body. The authors present a case and discuss the differential diagnosis of an inflammatory duodenal mass. Both symptomatology and radiological findings suggested a more sinister cause, such as a malignancy. However, histological analysis revealed normal mucosa and after conservative management the mass spontaneously resolved.

Inflammatory pseudotumour of the post-bulbar duodenum

The cases of five patients with upper gastrointestinal barium examination findings suggestive of a post-bulbar duodenal tumour are presented. Further investigations failed to confirm evidence of a neoplasm, but instead identified post-bulbar duodenal ulceration or scarring. Possible causes for these findings, technical considerations for avoiding this pitfall, and the importance of appropriate further investigations are discussed.
