[Pseudo-tumoral suprarénal-renal dysgenesis (author's transl)].

Intimate fusion of the renal and suprarenal parenchyma, associated with cystic lesions in the zone of tissue juxtaposition, constitutes a form of suprarenal-renal dysgenesis for which the name "dystopia" has been suggested. The distinction must be made from suprarenal-renal adhesions in which a connective tissue barrier between the two parenchymas persists. In this present case, the malformation gave rise to a pseudo-tumoral syndrome of rapid appearance in association with a haemorrhage. Removal of the kidney cannot be avoided in view of the absence of any plane of cleavage with the suprarenal when the suprarenal tumour is removed.
