CT diagnosis and analysis of 30 cases traumatic rupture of spleen

目的:讨论外伤性脾破裂的CT诊断表现。方法:对30例外伤性脾破裂患者进行了CT诊断与手术证实。结果:脾周新月形等低密度混杂影是外伤性脾破裂的主要CT表现。脾包膜下血肿表现沿脾侧边缘向外新月形低密度影,增强脾实质明显强化,但血肿不强化。脾内血肿呈类圆形或斑片状高密度影,脾撕裂伤在脾实质内见低密度带。结论:CT平扫及增强扫描能明确诊断外伤性脾破裂。

Objective：discussion of CT diagnosis of traumatic rupture of spleen.Methods：CT diagnosis and opera- tive approval to 30 cases traumatic rupture of spleen at hospital.Result：traumatic rupture of spleen mainly features crescent and low-density mix shadow around the spleen by the CT imaging, according to CT scanning, hematoma un- der the capsule of spleen shows a crescent and low-density shadow which is outward along the spleen edge, when scanning is enhanced, the shadow marking spleen substance becomes thicker, but the shadow marking the hematoma won＇t be. The hematoma within spleen shows round or patchy and high-density shadow, rupture of spleen usually shows low-density shadow within spleen substance. Conclusion： traumatic rupture of spleen can be approved by com- mon and enhance scanning with CT diam^osis.
