Paediatric ImagingRetroperitoneal tumour
a
tumour arising in the retroperitoneum. Technically, any
tumour arising in the pancreas, adrenal gland or kidney is a retroperitoneal
tumour, but the term is conventionally used to describe retroperitoneal teratomas or sarcomas (
Fig.1). The most frequent
benign tumour arising in the retroperitoneum is a
lymphangioma.
