Duodenal pseudotumour: a silent impacted common bile duct calculus
Postgraduate Medical Journal
|October 1, 1989
Summary
A gallstone impacted in the bile duct can mimic a duodenal tumor, causing dyspeptic symptoms. Endoscopic treatment successfully resolved this rare but treatable condition.
Area of Science:
- Gastroenterology
- Diagnostic Imaging
Background:
- Barium meals are used to investigate upper gastrointestinal symptoms.
- Duodenal tumors can present with dyspeptic symptoms.
Observation:
- A patient with dyspeptic symptoms was found to have a duodenal filling defect on barium meal.
- Initial diagnosis suggested a duodenal tumor.
Findings:
- Further investigation revealed the defect was a pseudotumor caused by a gallstone impacted in the distal common bile duct.
- Endoscopic sphincterotomy was performed for treatment.
Implications:
- Impacted gallstones in the common bile duct can present as pseudotumors, mimicking duodenal neoplasms.
- This condition is treatable with endoscopic sphincterotomy.
- Radiologists and gastroenterologists should consider gallstone impaction in the differential diagnosis of duodenal filling defects.
