RESUMEN
OBJECTIVES: The use of drug therapy based on cabergoline, octreotide and long-acting release (LAR) octreotide has presented varying results in the treatment of GH excessive production in patients with McCune-Albright Syndrome. METHODS: We report the case of a 29 year-old female patient presenting McCune-Albright Syndrome and complaint of excessive bone growth. RESULTS: The patient presented a pituitary adenoma involving the right internal carotid artery and excessive secretion of growth hormone (no GH suppression was observed after the oral glucose tolerance test). Due to the presence of diffuse thickness in skull base bones, surgical approach was not considered effective and the patient was submitted to drug therapy with octreotide LAR and cabergoline. At the one year follow-up, GH and IGF-1 levels were normal and no adverse effects were present. CONCLUSION: The use of drug therapy based on the association of cabergoline and octreotide is safe and able to achieve complete hormonal control in the treatment of acromegaly for McCune-Albright patients.

OBJETIVO: O uso de terapia medicamentosa, como cabergolina, octreotide e octreotide de longa duração, tem apresentado resultados variados no tratamento da produção excessiva de hormônio de crescimento (GH) em pacientes com síndrome de McCune-Albright. MÉTODOS: Foi relatado o caso de uma paciente de 29 anos apresentando síndrome de McCune-Albright com queixas de crescimento ósseo excessivo. RESULTADOS: A paciente apresentava adenoma pituitário com envolvimento da artéria carótida interna direita e produção excessiva de GH (sem supressão de GH após o teste de supressão com glicose). Por causa do aumento importante da espessura dos ossos da base do crânio, a abordagem cirúrgica foi considerada pouco efetiva e a paciente foi submetida à terapia medicamentosa com octreotide de longa duração e cabergolina. No seguimento de um ano, os níveis de GH e IGF-1 estavam normais e os efeitos adversos não eram presentes. CONCLUSÃO: A terapia medicamentosa fundamentada na associação de cabergolina e octreotide é segura e capaz de alcançar controle hormonal completo no tratamento de acromegalia na síndrome de McCune-Albright.
