title: [The role of dynamic contrast-enhanced magnetic resonance imaging in diagnosis of torsion of the testicular appendix : a case report].
abstract: A 7-year-old male presented to our hospital with pain and swelling in the right scrotum for 9 days. On physical examination a swollen right scrotum was noted and right side cremasteric reflex disappeared. Ultrasound examination showed enlarged right testis and epididymis. Subsequent dynamic contrast enhanced magnetic resonance imaging (MRI) showed a 7 mm area of high signal intensity anterior to the right testis on coronal imaging of T2-weighted. Subtraction MRI revealed testicular perfusion and a nonenhanced mass was also identified anterior to the right testis. These findings indicated a diagnosis of torsion of the testicular appendix. We performed excision of the torsed appendage.
