RESUMO
El craneofaringioma es un tumor intracraneal histológicamente benigno y frecuentemente quístico que puede presentar un comportamiento agresivo por compresión de estructuras vecinas. Su manejo terapéutico es complicado ya que si bien el tratamiento de elección suele ser la cirugía, esta no está exenta de una gran morbimortalidad y recidiva tumoral frecuente. En aquellos craneofaringiomas con un componente quístico importante la irradiación interna del tumor con isótopos radiactivos supone una alternativa a los tratamientos convencionales. Se presentan 4 casos de pacientes con craneofaringiomas quísticos tratados mediante administración intraquística con 90Y-coloide y su evolución después del tratamiento(AU)
Craniopharyngioma is a histologically benign and frequently cystic intracranial tumor. It may present aggressive behavior due to compression of nearby structures. Its therapeutic management is complicated because, although surgery is the usual treatment of choice, it is not exempt of high morbidity and mortality, and frequent tumor recurrence. In craniopharyngiomas with a significant cystic component, internal irradiation with radioactive isotopes is a therapeutic alternative to conventional treatments. We present the cases of four patients with cystic craniopharyngiomas who were treated with intracystic administration of 90Y-colloid, and their evolution after the therapy(AU)
