Yolk tumor on testicular ectopia about a case and review of the literature: Contribution of imaging

Vitellin or endodermal sac tumours are rare germ malignant tumours. They account for less than 5% of germ cell tumours. They are aggressive tumors that preferentially affect children and young people. We illustrate here the importance of multimodality imaging for the diagnosis of vitellin sac tumor so we present a literature review about the case studied.
