摘要
目的:探讨副脾的螺旋CT影像特征及其误诊原因分析。方法:对23例经手术病理或临床随访证实的副脾患者的CT典型与不典型表现及临床资料进行回顾分析。结果:23例中,单发17例,多发6例。左侧肾上腺区11例,脾周或脾区12例。1例副脾伴梗死表现为均匀囊性病灶,无强化;其余22例CT均表现为平扫呈大小不等的软组织结节,密度均匀,边界清晰,CT值均在45HU以上;增强后均匀明显强化,增强程度均在50HU以上。结论:副脾有典型的影像学表现及常见发生部位,多数可在术前作出明确诊断,但副脾毗邻肾上腺或有伴发病变者常致术前误诊。
Objective:To explore the CT imaging features of accessory spleens and the possible causes of their misdiagnosis. Methods:CT findings and clinical data of 23 cases of accessory spleens with typical and atypical CT manifestations confirmed by postoperative pathology or clinical follow-up were retrospectively analyzed. Results: Among 23 cases, single accessory spleen was found in 17 cases,and multiple accessory spleen in 6 cases. The lesions of 11 cases were located in left adrenal region,and 12 cases in perisplenic and splenic region. One case of accessory spleen with infarction presented itself with uniform cystic lesion without enhancement in CT findings,the other 22 cases appeared as soft tissue nodules with varied sizes, uniform density and well defined margin in plain CT scan. The CT values of all were above 45 HU, with intensive enhanced imaging after contrast application, and the enhancement degree of all was above 50HU. Conclusion: CT findings can help make correct preoperative diagnosis for most accessory spleen cases according to their imaging features and preferable location. Misdiagnosis often occurrs when the accessory spleens are near the adrenal gland or complicated with lesions.
