Oftalmopatía distiroidea asociada a hipotiroidismo / Dystrophy ophthalmology associated with hypothyroidism

RESUMEN

Caso clínico La oftalmopatía por enfermedad de Graves (exoftalmos, infiltración muscular y palpebral) se asocia casi sistemáticamente a hipertiroidismo. Paciente diagnosticada de hipotiroidismo subclínico 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

ABSTRACT

Clinical 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
