Summary

Duodenal carcinoids are rare tumors most often found in the proximal duodenum. Imaging reveals them as intraluminal polyps or mural masses, with diverse clinical and pathological features.

Area of Science:

  • Gastrointestinal Radiology
  • Oncology
  • Pathology

Background:

  • Duodenal carcinoids are uncommon neuroendocrine tumors.
  • These tumors present a wide spectrum of clinical and pathological features.
  • Understanding their imaging characteristics is crucial for diagnosis and management.

Purpose of the Study:

  • To retrospectively evaluate the imaging features of duodenal carcinoids.
  • To correlate imaging findings with clinical and pathological data.

Main Methods:

  • Retrospective review of barium studies, computed tomographic (CT) scans, and magnetic resonance (MR) images.
  • Analysis of pathology reports, gross pathology photographs, and clinical data from 33 patients.
  • Consensus evaluation of imaging studies by two abdominal radiologists for mass characteristics and contrast enhancement.

Main Results:

  • Most duodenal carcinoids were located in the proximal duodenum (bulb and second portion).
  • Common imaging manifestations included intraluminal polypoid masses (52%) and mural masses (39%).
  • CT demonstrated heterogeneous contrast enhancement; associated conditions included Zollinger-Ellison syndrome and neurofibromatosis type 1 (NF-1).

Conclusions:

  • Duodenal carcinoids are uncommon tumors with diverse presentations.
  • They predominantly occur in the proximal duodenum.
  • Imaging findings typically manifest as intraluminal polyps or mural masses.
