目的探讨小儿非外伤性睾丸急症的MSCT表现及其临床应用价值。方法回顾性分析17例行MSCT检查并经临床、手术及病理证实的小儿非外伤性睾丸急症病例资料。结果急性睾丸和(或)附睾炎13例,表现为睾丸体积肿大,密度可不均,鞘膜积液明显;增强后睾丸及鞘膜较明显不均匀强化;患侧精索增粗,强化较健侧明显。睾丸扭转4例,表现为睾丸肿大,密度不均,内见高低混杂密度影;增强后睾丸轻度不均匀强化;精索增粗,强化程度不及健侧精索。结论小儿非外伤性睾丸急症影像特征随病变发展有多种表现,MSCT能从形态上全面、直观、多方位、多角度显示病变细节及与邻近解剖结构的关系,结合增强扫描可进一步明确病变性质,在诊断和鉴别诊断小儿非外伤性睾丸急症中具有重要价值。
Objective To investigate the manifestation and clinical value of MSCT in children with non-traumatic testicular emergency. Methods Retrospective analysis of 17 cases of pediatric non-traumatic testicular emergency with MSCT confirmed by clinical, surgical and pathological evidence. Results Acute testicular and / or epididymitis in 13 cases, showing the testicular volume enlargement, density can be uneven, clear hydrocele; after enhanced testis and sheath more obvious uneven enhancement; ipsilateral spermatic cord thickening, strengthen the more Contralateral obvious. Testicular torsion in 4 cases, manifested as testicular enlargement, uneven density, see the level of mixed density within the shadow; enhanced slightly uneven testicular enhancement; spermatic cord thickening, strengthening less than the contralateral sphincter. Conclusion The imaging features of children with non-traumatic testicular disease have many manifestations with the development of lesions. MSCT can display the details of lesion and the relationship with the adjacent anatomical structures in a comprehensive, intuitive, multi-directional and multi-perspective manner. MSCT can further clarify the lesion characteristics , In the diagnosis and differential diagnosis of pediatric non-traumatic testicular emergency has important value.
