宝石能谱CT诊断腹腔自体异位脾种植1例并文献复习

Diagnosis of Abdominal Cavity Ectopic Splenic Autotransplantation with Gemstone Spectral CT: A Case Report Combined with Literature Review

目的:探讨宝石能谱CT对腹腔自体异位脾种植的诊断价值,并对其临床特点和影像表现进行文献复习。方法:对一例脾外伤患者行宝石能谱CT扫描,观察肿瘤强化模式及能谱曲线表现。结果:肝右叶包膜外、纵横裂区、脾区见单发或簇状多发富血供结节,大小0.64×1.14 cm^4.94×1.81 cm,动脉期呈"花斑状"强化,门静脉期、延迟期对比剂廓清程度趋于一致。能谱曲线示肝右叶包膜外、纵横裂区、脾区结节曲线斜率及走行趋势近似相同。结论:宝石CT能谱曲线斜率有助于腹腔自体异位脾种植诊断。

Objective： To detect the diagnostic value of Gemstone Spectral CT for abdominal cavity ectopic splenic autotransplantation and review the literatures about the clinical characteristics and imaging findings. Methods： A case of splenic trauma patient underwent Gemstone Spectral CT scan, observed the masses enhancement patterns and performance of the spectral curves.Results： There were hypervascular nodules in extracapsular right lobe, vertical and horizontal split plot, size 0.64×1.14 cm- 4.94×1.81 cm. Nodules were ＂piebald＂enhanced in arterial phase. Degree of contrast medium clearance was consistent in the portal venous phase and delayed phase. Spectral curves also showed similar slope of curves. Conclusion： Abdominal cavity ectopic splenic autotransplantation can be diagnosed with Gemstone Spectral CT combining slope of the curves and enhancement status.
