RESUMO
In this case report, we highlight four different cases of ectopic adrenocorticotropic hormone (ACTH) secretion with different pitfalls in the diagnostic workup. Ectopic ACTH secretion (EAS) is an uncommon cause of Cushing's syndrome that accompanies a variety of tumours. It is associated with significant morbidity and mortality. This underlines the importance of early and adequate diagnosis. We will review the causes of EAS and their presentation to increase awareness of this rare and progressive disease.

A case of suspected thyroid stunning is presented in a previously hyperthyroid patient with a diffuse goiter, who had undergone a 185 MBq (131)I-NaI thyroid scan shortly before a (99m)Tc-pertechnetate scan. A less likely alternative hypothesis is the development of early hypothyroidism, 3.5 weeks after a modest (131)I dose.
