MRI detection of suprasellar germinoma causing central diabetes insipidus.

摘要: This is a case report of an 18-year-old man with central diabetes incipidus (DI). An MRI done three months after the onset DI did not disclose responsible lesion. Four later, second showed location tumor origin at upper pituitary stalk and median eminence. Eight occupied hypothalamic area. The became large contrast-making enough to be visible on between 3 4 onst DI. Besides suprasellar tumor, another mass was noted in pineal region. growth pattern latter corresponded well that former. Although sensitive diagnostic tool for detection intracranial tumors, no adequate rationale has been given as how might repeated children adolescents who have diagnosed having DI, when their initial MRIs may normal. In our patient, superconductive thin slice revealed germinoma onset. tumors this originated developed simultaneously. indicate multi-center tumor. Another possibility very early dissemination from development.
