Abstract
Purpose: To analyze the characteristics of CT and MR of duodenal stromal tumors. Materials and Methods: The CT and MR findings of 16 patients with primary duodenal stromal tumors were analyzed retrospectively, and compared with their pathological results. CT scanning were performed in 12 cases and MR in 4 cases. Results: Pathological report: borderline tumor 5 cases, low-grade malignant tumor 4 cases, moderate /high-grade 7 cases. On CT/MRI, the lesions presented as round and lobulated solid Masses and cystic-solid mixed masses. On non-enhanced CT/MRI, the lesions appeared as mixed density/signal intensity masses. After contrast administration, the solid masses and the solid portions of the tumors demonstrated significantly enhancement in arterial phases and still keep enhancement the portal phases. The non-enhancement portions represented necrosis. Calcification was found in 3 cases and air-filled cavity in Scases. Conclusion: The findings of CT and MRI of duodenal stromal tumors were related with their pathological characteristics. CT and MRI can supply valuable information for the locations of duodenal stromal tumors, and MRI was more effective in displaying hemorrhage, cystic degeneration of the lesions than CT.关键词
