摘　　要：目的:分析14例胰尾、脾门区域占位病灶CT表现,提高对胰尾、脾门区病变的诊断能力。方法:对14例病例行CT平扫增强,并行多平面重建(MPR)后结合临床病理做探讨分析。结果:14例胰尾、脾门区占位病灶包括胰尾神经内分泌癌、副神经节瘤、胰尾实性假乳头瘤各1例,胰腺囊腺癌2例,胰腺炎假囊肿2例,脾原发淋巴瘤3例,胃恶性间质瘤及胃平滑肌肉瘤各2例。本组胰尾、脾门区良性病变占14.3%,恶性病变占85.7%。CT诊断正确9例,占64.3%。结论:胰尾、脾门区域一些占位病灶CT诊断有相当的难度,只有对影像资料作全面仔细分析并结合临床病史才能提高诊断的准确性。Objective：To explore the CT image characteristics of lesions at hilum of spleen and tail of pancreas so as to improve the diagnosis of these diseases.Methods：CT appearances of 14 cases with lesions at hilum of spleen and tail of pancreas were analysed correlatively with pathological results and clinical symptoms.14 cases all underwent plain CT scan and contrast-enhanced CT scan,proceeding with MPR.Results：Fourteen lesions one patient with neuroendocrine carcinoma of pancreatic tail,one patient with paraganglioma and one patient with solid pseudopapillary tumor of pancreatic tail,two patients with cystadenosarcoma of pancreas,two patients with pseudocyst of pancreas,three patients with lymphoma of pancreas,two patients with malignant interstitialoma of stomach,and two patients with leiomyosarcoma of stomach.In this group,85.7% of lesions were malignant and 14.3% were benign.The coincidence and misdiagnosis rate of this group was 64.3% and 35.7% respectively.Conclusion：Accurate diagnosis of lesions of hilum of spleen and tail of pancreas can be reached only by strictly analyzing the imaging characteristics and clinical manifestations.
