[Dissociation between absorption of 131I-19-iodocholesterol and hormonal activity in corticosteroma patients].

A case is described without clinical and hormonal data about Icenko-Cushing syndrome, with a scintigraphy of adrenals demonstrating the image, characteristic for corticosteroma (decompensated node). The most probable explanation of the finding is that the tumour is with restricted secretory possibilities and secrets mainly biologically inactive hormones, and furthermore it is not with an autonomous, but ACTH-dependent hormonal production.
