Two children with ganglioneuroma and ganglioneuroblastoma had bilateral heel cord shortening. In one child, the Achilles tendons were lengthened surgically prior to removal of the tumor. In the other child, the heel cord shortening corrected itself spontaneously following removal of the retroperitoneal tumor. One patient had associated hypertension and the other, chronic diarrhea. It is suggested that shortening of the Achilles tendons was in some way related to the ganglioneuroblastoma and should be considered as a possible early diagnostic sign.
