RESUMENCaso clínico: La oftalmopatía por enfermedad de Graves (exoftalmos, infiltración muscular y palpebral) se asocia casi sistemáticamente a hipertiroidismo. Paciente diagnosticada de hipotiroidismo subclíni-co y tratada adecuadamente con tiroxina oral. Unos meses después desarrolla un exoftalmos bilateral y simultáneamente presenta anticuerpos séricos antireceptor de TSH positivos. Se suspende entonces el tratamiento con tiroxina, y se comprueba que el hipotiroidismo ha progresado hasta hacerse primario. Se establece el diagnóstico de enfermedad de Graves hipotiroidea. Discusión: El diagnóstico se basó en la existencia de la oftalmopatía y los anticuerpos positivos, ambos específicos de la enfermedad de Graves. La coexistencia de hipotiroidismo es excepcional, pero posible.Palabras clave: Oftalmopatía por enfermedad de Graves, hipotiroidismo, anticuerpos anti-receptor de tirotropina, tiroxina, terapéutica.

ABSTRACTClinical case: Graves´ ophthalmopathy (exophthalmos, muscular and eyelid infiltration) is associated almost systematically to hyperthyroidism. A female patient was diagnosed with subclinical hypothyroidism and treated with oral thyroxine. Months later she developed bilateral exophthalmos and was serum-positive for thyrotropin receptor antibodies. Thyroxine treatment was suspended, and it was verified that her condition had developed into primary hypothyroidism. A diagnosis of Graves' disease with hypothyroidism was made. Discussion: The diagnosis was based on the existence of ophthalmopathy and positive serum antibodies, both specific indicators of Graves' disease. The coexistence of hypothyroidism with Graves' disease is exceptional, but possible (Arch Soc Esp Oftalmol 2007; 82: 765-768).
Pituitary macroadenomas (more than 10 mm in diameter) are infrequent as casual findings and optimal management strategy for these tumours has not been established. Neurosurgical approach must be always considered in patients with visual field defects or with hormone-secreting adenomas (but prolactinoma), and in those with evidence of lesion's growth or if clinical pituitary apoplexy occurs. We present two cases in which surgical indication was based on patient's young age (case number one), and on hypogonadal status, in a male patient not suitable of androgen substitution (case number two). We also discuss the benefits of including such unusual indications for neurosurgical treatment into the incidentally discovered pituitary macroadenomas evaluation strategy.
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.
