[Extreme kidney displacement caused by an adrenal pseudocyst]

Renal displacement is very infrequently associated with a space occupying adrenal disease and sometimes imposes major diagnostic problems. The diagnosis of monstrous, retroperitoneal cysts is of particular difficulty. In a 51-year-old female patient the diagnosis and the association of a cystic formation to the adrenal gland could only be made at surgery, despite the steadily increasing renal displacement. The etiology of adrenal cysts, the diagnostic procedures and the possible concurrence of hypertension are discussed.
