Giant splenic aneurysms larger than 8 cm (GSAA) are rare and often asymptomatic but present an increased risk of dramatic rupture, a life-threatening complication. The management of these aneurysms is especially challenging. We probably report the first case of GSAA revealed by clinical mechanical jaundice due to direct compression of the biliary tree. The lesion was diagnosed during abdominal ultrasound in a 68-year-old patient but determination of the specific splenic origin and extensive anatomic preoperative evaluation were achieved by MDCT. The case illustrates the new high quality performances of MDCT in the evaluation of complex vascular abdominal situations and is presented with a brief review of the relevant literature.
直径大于8厘米的巨大脾动脉瘤（GSAA）较为罕见，通常无症状，但破裂风险剧增，这是一种危及生命的并发症。此类动脉瘤的治疗极具挑战性。我们可能报道了首例因临床机械性黄疸而发现的GSAA，其病因是胆管树受到直接压迫。在一名68岁患者的腹部超声检查中发现了该病变，但通过MDCT实现了对脾脏特定起源的确定以及广泛的术前解剖学评估。该病例展示了MDCT在评估复杂腹部血管情况方面的新的高质量性能，并结合相关文献进行了简要综述。
