Аннотация
CONTEXT: Carcinoid tumors represent a group of well-differentiated tumors originating from the diffuse endocrine system outside the pancreas and thyroid. The overall prevalence of carcinoid tumors in the United States is estimated to be one to two cases per 100,000 persons. Various sites of origin of this neoplasm are appendix - 30-45%, small bowel - 25-35% (duodenum 2%, jejunum 7%, ileum 91%, multiple sites 15-35%), rectum 10-15%, caecum - 5%, and stomach - 0.5%. Liver metastases from jejunal and ileal carcinoids are generally hypervascular.
CASE REPORT: Here we report a case of primary jejunal carcinoid tumor in a 66-year-old woman metastasizing to liver with ultrasonography, computed tomography, and diffusion-weighted magnetic resonance imaging (DWI) findings.
CONCLUSION: Primary jejunal carcinoid tumor is a rare entity. DWI can help in the differential diagnosis of hepatic hypervascular metastatic mass lesions from benign ones, as well as in the diagnosis of carcinoid tumor.
