Neuroblastoma with spermatic cord metastasis in a child: Sonographic findings

We report a case of neuroblastoma in a patient who had no involvement of the spermatic cord at diagnosis but who developed spermatic cord metastasis 2 months later. The metastasis appeared on sonography as a hypoechoic, highly vascular, fusiform, hard, 14 × 10 × 7 mm mass located in the right inguinal canal and extending into the scrotum. The diagnosis of spermatic cord metastasis was confirmed by resection and histopathologic examination. We recommend that the scrotum and spermatic cord be evaluated by high‐resolution sonography in children with neuroblastoma, both at the time of diagnosis and during follow‐up. © 1999 John Wiley & Sons, Inc.
