【摘要】：目的探讨肾上腺区副脾的CT特征。方法回顾性分析经手术病理证实的5例肾上腺区副脾术前CT资料。结果病灶均位于左侧肾上腺区,单发,边界清晰,4例呈类圆形,1例椭圆形,最大径1.1~3.0 cm之间,平均(2.1±0.7)cm。CT平扫5例病灶密度均匀,与同层面的脾脏密度相近,均无囊变、坏死、出血及钙化,CT值41.9~55.3 HU,平均(47.7±5.4)HU;增强动脉期均明显不均匀或斑马纹样强化,CT值78.6~141.1 HU,平均(102.6±25.8)HU,静脉期2例进一步强化,3例强化程度略减低,强化程度均趋于均匀,CT值68.7~129.7 HU,平均(104.6±22.9)HU。5例病灶3期CT值与同层面脾脏的CT值相仿,5例中,病灶由脾动脉分支供血4例,合并其他部位的副脾2例。结论肾上腺区副脾CT特征为平扫密度及强化程度均相近,多由脾动脉分支供血,易合并其他部位的副脾,这些特征有助于肾上腺区副脾的诊断。
[Abstract]:Objective to investigate the CT features of adrenal accessory spleen. Methods CT findings of 5 cases of adrenal accessory spleen confirmed by surgery and pathology were retrospectively analyzed. The maximum diameter was between 1.1 and 3.0 cm, the mean value was 2.1 卤0.7 cm. Ct plain scan showed that the density of the lesions was uniform, similar to that of the spleen on the same plane, and no cystic degeneration or necrosis was found in all cases. The CT value of haemorrhage and calcification was 41.9 卤55.3 HUU (mean 47.7 卤5.4 HUU), the enhancement of arterial phase was obviously uneven or the CT value of zebra pattern enhancement was 78.6 卤25.8 HUU (mean 102.6 卤25.8 HUU), and the enhancement degree of 2 cases with further enhancement in venous phase was slightly decreased. The enhancement degree tended to homogenize with the CT value of 68.7 ~ 129.7 HU.The mean CT value of the lesions in the 5 cases was 104.6 卤22.9HU, which was similar to the CT value of the same plane spleen in 5 cases, and the focus was supplied by the branches of the splenic artery in 4 cases. ConclusionThe CT features of adrenal accessory spleen are similar in density and enhancement, most of them are supplied by splenic artery, and they are easy to be combined with the accessory spleen of other parts. These characteristics are helpful for the diagnosis of adrenal accessory spleen.
