摘　　要：A 57-year-old male presenting with spontaneously relieved abdominal cramp and distension was admitted to theWest China Hospital.The diagnosis remained unclear after colonoscopy and computed tomography.Double contrast-enhanced ultrasonography was then performed and a neoplasm in the small intestine was suspected,supported by a thin-section computed tomography and positron emission tomography/computed tomography.This was confirmed pathologically after surgery to be a small intestinal G1 neuroendocrine tumor.Surgery was performed to remove approximately 25 cm of small bowel and a 3-cm solid mass located in the mesentery.The patient had a complete recovery and was tumor-free at the final follow-up.Small intestinal tumors including neuroendocrine tumors have always posed a diagnostic challenge.This case indicated that double contrastenhanced ultrasonography is feasible in detection of small intestinal neuroendocrine tumors,and it may be an advisable approach assisting diagnosis of small intestinal tumors.
