小儿非外伤性睾丸急症MSCT表现(附17例分析)

The MSCT Diagnosis of Nontraumatic Testicular Emergency in Children (A Report of 17 Cases)

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 value of MSCT in the diagnosis of nontraumatic testicular emergency in chil- dren. Methods MSCT findings of 17 patients with nontraumatic testicular emergency confirmed by clinical, surgery and pathology were analyzed retrospectively. Results There were 13 cases of testicular epididymitis manifested as the enlarge- ment of testis companied with inhomogenerous density, hydrocele obviously and significantly heterogeneous enhancement of testis and sheath; the ipsilateral spermatic cord was thickened and significantly enhanced compared with the contralateral. There were 4 cases of testicular torsion presented with the enlargement of testis, inhomogeneros density, testis could be het- erogeneously enhanced slightly, spermatic cord could be enlarged and enhanced which the degree was less than the contra- lateral normal spermatic cord. Conclusion The image features of nontranmatic testicular emergency in children are com- plicated at different stages, which can be accurately manifested by MSCT, MSCT has an important value in the diagnosis and differential diagnosis of nontraumatic testicular emergency in children.
