Neuroblastoma with spermatic cord metastasis in a child: Sonographic findings

We report a case of neuroblastoma in a patient who had no involvement of th e spermatic cord at diagnosis but who developed spermatic cord metastasis 2 months later. The metastasis appeared on sonography as a hypoechoic, highl y vascular, fusiform, hard, 14 x 10 x 7 mm mass located in the right inguin al canal and extending into the scrotum. The diagnosis of spermatic cord me tastasis was confirmed by resection and histopathologic examination. We rec ommend that the scrotum and spermatic cord be evaluated by high-resolution sonography in children with neuroblastoma, both at the time of diagnosis an d during follow-up.
