RESUMO
Infundibuloneurohypophysitis is a rare condition, which is part of the group of hypophysitis, of relatively recent description (1993). The main clinical manifestation is diabetes insipidus, whose natural evolution is towards chronicity. The differential diagnosis with other thickening of the hypophysial stem is very important, where the clinic, imaging, laboratory and eventually biopsy are a main support for a correct diagnosis. We present a clinical case that shows the usual picture of infundibuloneurohypophysitis, and illustrates the imaging evolution in a female patient, with diabetes insipidus as the main clinical manifestation

Partial forms of diabetes insipidus (DI) can be combined sometimes with alterations in the functionality of antidiuretic hormone (ADH) as a result of other co-morbidities. These entities are sometimes combined, it being necessary to assess this possibility further diagnostic protocols in particular cases. If clinical patient is within the spectrum of a DI of neurohypophyseal origin is described.
