Summary
Colonic amyloidosis, though common, rarely shows on imaging. This case highlights a perforated giant colonic diverticulum in a renal transplant patient, linking amyloidosis to this rare condition.
Area of Science:
- Gastroenterology
- Nephrology
- Radiology
Background:
- Colonic amyloidosis is a frequent condition but often lacks specific radiographic findings.
- Giant colonic diverticulum (GCD) is a rare entity with varied and nonspecific radiological presentations.
Observation:
- A case of perforated GCD diagnosed via helical CT is presented.
- The patient was a renal transplant recipient with a history of long-term hemodialysis.
Findings:
- Pathological examination confirmed amyloid deposition in the affected colon.
- Helical CT successfully diagnosed the perforated giant colonic diverticulum.
Implications:
- Amyloidosis may play a role in the pathogenesis of giant colonic diverticulum.
- Giant colonic diverticulum should be considered within the gastrointestinal manifestations of amyloidosis.
