Diferencial de diagnóstico para amenorrea secundaria con prueba de estrógeno y progesterona negativa

  • Diagnóstico más probable:
    • a) Hipotálamo: La falta de estrógeno y progesterona sugiere un problema en la regulación hormonal, y el hipotálamo es el principal regulador de la función hormonal en el eje hipotálamo-hipofisario-ovariano.
  • Otros diagnósticos probables:
    • c) Hipofisis: La hipofisis es otro posible lugar de lesión, ya que es responsable de la producción de hormonas que estimulan la ovulación y el crecimiento del endometrio.
  • No debes perder de vista (diagnósticos que no son tan probables, pero que serían mortales si se pierden):
    • Ninguna de las opciones anteriores: Aunque no es el diagnóstico más probable, es importante considerar la posibilidad de una lesión en el útero o en otros órganos que puedan afectar la función menstrual.
  • Diagnósticos raros:
    • b) Útero: Aunque es posible que una lesión en el útero cause amenorrea secundaria, es menos probable que sea la causa principal de la falta de estrógeno y progesterona.
    • Otras opciones: Enfermedades raras como la insuficiencia ovariana prematura, la enfermedad de Asherman, etc. También podrían ser consideradas, aunque son menos probables.
