Empty sella syndrome
Empty sella syndrome (Benign intracranial hypertension) is a developmental disorder of small-breed dogs characterized by herniation of the subarachnoidal space into the sella turcica with invisible (total empty sella) or reduced (partial empty sella) hypophyseal size.
An empty sella syndrome can be associated with endocrine disturbances such as central hyperadrenocorticism due to significantly small or absent adenohypophysis, but is very rare.
Hydrocephalus has not been reported with this condition in dogs, although it does occur in humans.
These cases have been treated symptomatically with attention to secondary disease, resulting in resolution of clinical signs in most cases.
