RESUMO

Klinefelter Syndrome is the most frequent cause of hypergonadotropic hypogonadism in men. A flat response at luteinizing hormone releasing hormone stimulation test could be the first sign of hypothalamic tumor in these patients. We report the case of a patient diagnosed by neonatal screening with Klinefelter Syndrome, 47 XXY, that at 17 years follow-up presents analytical modification of the response to luteinizing hormone releasing hormone stimulation test with suppressed luteinizing hormone and follicle-stimulating hormone values; lately he presents with headache and loss of left eye vision. A magnetic resonance imaging of the brain showed a mixed germ cell hypothalamus tumor, requiring surgery, chemotherapy and radiotherapy with optimal response.

RESUMO

El síndrome de Klinefelter es la causa más frecuente de hipogonadismo hipergonadotropo en el varón. La supresión en la respuesta al estímulo con hormona liberadora de la hormona luteinizante en estos pacientes debe hacer sospechar como posible etiología una tumoración a nivel hipotalámico. Se presenta el caso de un paciente diagnosticado a los 4 meses con síndrome de Klinefelter mediante cribado neonatal, con cariotipo 47 XXY, en el que se realizan controles clínicos y analíticos seriados y se encuentran, a los 17 años, valores suprimidos de hormona luteinizante y hormona folículo estimulante. Inicia, posteriormente, cefalea y amaurosis de ojo izquierdo, y se encuentra, en una resonancia magnética cerebral, un tumor germinal mixto a nivel hipotalámico, que precisa tratamiento quirúrgico, quimioterapia y radioterapia, con respuesta favorable.(AU)
