摘　　要：功能性胰岛素瘤约占胰岛素瘤的85％，多为单发，患者有明显内分泌紊乱的临床表现，92％以神经症状为主。其定性诊断不难，但由于瘤体常较小，术前定位困难。因此，术前明确原发病灶的位置及大小对于手术方案的选择十分重要。Functional insulinoma accounts for 85% of insulinoma, and it is evenly distributed in the head, body and tail of the pancreas. The main clinical manifestation of patients with functional insulinoma is endocrine disorder, and 92% of them presented with neurological symptoms. Preoperative localization of functional insulinoma is difficult because of the small size of the tumor. A 31-year-old male patient with the chief complaint of paroxysmal dizziness and confusion was admitted to the First Affiliated Hospital of Kunming Medical College on May 3,2010. The patient was preliminarily diagnosed with functional insulinoma by detecting the levels of fasting blood glucose,serum insulin and fasting serum C-peptide, as well as the presence of Whipple＇s triad. Ultrasonography and enhanced computed tomography demonstrated that a well-defined tumor of 13.0 mm ×13.0 mm in size was located in the pancreatic uncinate process.On May 27, 2010, the patient received surgical resection of the tumor, and histological examination of the resected specimen confirmed insulinoma.
