Aneurysms originating in the superior mesenteric vein are extremely rare: 4 cases have been reported in the international literature. The authors describe a case of a female patient admitted to hospital for vague abdominal pain. The CT findings revealed a cyst-like neoformation. By means of angiography it was then identified as a dilatation of the superior mesenteric vein. The causes of such dilatations are not altogether clear. Current interpretations refer to possible congenital and acquired factors, as well as trauma. The accompanying symptoms are abdominal pain, icterus, gastrointestinal haemorrhage or portal hypertension, but occasionally patients may present no symptoms whatsoever.
国际文献中仅报道过4例。作者描述了一名因腹部隐痛入院的女性患者。CT检查结果显示有一个囊肿样新生物。通过血管造影，该新生物被确定为肠系膜上静脉扩张。此类扩张的病因尚不完全清楚。目前的解释涉及可能的先天性和后天性因素，以及创伤。伴随症状有腹痛、黄疸、胃肠道出血或门静脉高压，但患者偶尔可能毫无症状。
