A male infant presenting with paraplegia due to intraspinal
extension of an endodermal sinus tumour in the posteroinferior mediastinum
is reported. Dumbbell tumours are usually observed in mediastinal neuroblastomas,
and rarely in rhabdomyosarcomas of the chest wall. The present case demonstrates
the clinical similarity of endodermal sinus tumours to neuroblastomas with
extradural extension. Therefore, endodermal sinus tumours should be considered
in the differential diagnosis of posterior mediastinal masses, because of
the distinctly different treatment from that for other tumours.
