Duodenal Carcinoids: Imaging Features with Clinical-Pathologic Comparison

PURPOSE: To retrospectively evaluate the imaging features of duodenal carcinoids with clinical-pathologic comparison. MATERIALS AND METHODS: The institutional review board approved this study; informed consent was not required. The study was HIPAA compliant. The authors retrospectively reviewed the barium studies (n = 20), computed tomographic (CT) scans (n = 16), magnetic resonance (MR) images (n = 2), pathology reports (n = 33), gross pathology photographs (n = 15), and clinical data (n = 33) from 33 patients (16 men and 17 women; age range, 19–90 years; mean age, 52.6 years) with a confirmed diagnosis of duodenal carcinoid admitted into our institution during a 52-year period. The imaging studies were evaluated by consensus of two abdominal radiologists for the number of masses and their location and morphologic characteristics (polypoid or mural). The CT and MR images were also assessed for contrast enhancement characteristics. RESULTS: Most carcinoids were located in the proximal duodenum (10 in the ...
