Pituitary tumors, usually adenomas, account for about 10-15% of all intracranial tumors. Their treatment, which includes surgery, medicine or radiotherapy, either isolated or in combination, aims to halt tumor growth or achieve tumor shrinkage, as well as control hormone hypersecretion or ensure hormone replacement. Such approaches have made pregnancy possible for women with pituitary adenomas. Medical therapy with dopamine agonists is the treatment of choice for most patients with prolactinomas, with surgery reserved for individuals resistant to drugs. On the other hand, surgery before conception is indicated as a first-line approach in patients with acromegaly, Cushing disease or clinically nonfunctioning pituitary macroadenomas. In these patient populations, medical therapy with somatostatin analogues (acromegaly) or drugs that target the adrenal glands, such as metyrapone and ketoconazole (Cushing disease), should be reserved for those in whom surgery is unsuccessful or contraindicated.
RESUMOO hiperaldosteronismo primário (HAP) representa importante causa de hipertensão arterial secundária, potencialmente curável, que tem recebido atenção recente em função do aumento de sua prevalência desde a introdução do rastreamento pelo uso da relação aldosterona/atividade plasmática de renina. Apresentamos caso de HAP causado por provável aldosteronoma, coexistente com adenoma adrenal não-funcionante contra-lateral, o que dificultou o diagnóstico etiológico. Discutimos as formas mais apropriadas de rastrear, confirmar o diagnóstico de HAP e diferenciar as suas diversas etiologias, com destaque para o papel do cateterismo de adrenais no diagnóstico diferencial definitivo entre aldosteronoma e hiperaldosteronismo idiopático, com implicações no sucesso terapêutico. Primary aldosteronism (PA) represents an important cause of secondary hypertension, potentially curable, and it has been receiving particular attention due to its increasing prevalence, after the beginning of the use of plasma aldosterone concentration to plasma renin activity ratio as a screening method. We present a case of PA caused by an aldosteronoma associated with a contralateral nonfunctioning adrenal adenoma, which resulted in difficulties in the final diagnosis. We discuss the most appropriated tests to screen, confirm the diagnosis of PA and define the etiology of the disorder, especially the adrenal veins sampling to distinguish the aldosteronoma and idiopathic hyperaldosteronism and to guide successful treatment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
