Objective:
To evaluate through MR the presence or absence of the normal hyper-intense signal of the posterior pituitary lobe in four patients diagnosed of familial central diabetes insipidus.
Patients And Methods:
The posterior pituitary lobe was studied by magnetic resonance imaging in four patients, three children and one adult, diagnosed of familiar central diabetes insipidus.
Results:
In none of the four patients could the normal posterior bright signal be detected.
Conclusion:
The normal hyper-intense MR image of the neurohypophysis is suggested to reflect its function and its absence is frequent in patients diagnosed of familial central diabetes insipidus.
