MRI features of testicular torsion:compared to surgery and pathology / 实用放射学杂志

ABSTRACT

Objective To discuss the MRI features of testicular torsion,and to improve the clinical and imaging understanding. Methods 8 cases of testicular torsion confirmed by surgery and pathology were included in this study,the MRI signs and clinical data were compared and analyzed.2 underwent MRI conventional scan,6 underwent both MRI conventional and enhanced scan.Results The median age of testicular torsion male patients was 16.7 years,attack time 4.0-24.0 h.In MRI,there were 6 cases(75.0%)with testis and epididymis volume augmented,2 cases(25.0%)with increase of testicular signal strength in T1WI sequence,4 cases(50.0%) with decrease of testicular signal strength in T2WI sequence,8 cases(100.0%)with tortuosity,enlargement,nodules of spermatic cord,6 cases(75.0%)with decreased enhancement in testis and epididymis.Conclusion Tortuosity,enlargement of spermatic cord and decreased enhancement in testis and epididymis are the MRI features of testicular torsion.
