An empty sella is frequently and incidentally observed in MRI scans. The hallmark of the finding is, as the name suggests, a pituitary fossa which is largely empty of tissue, replaced by CSF. 

Most patients with empty sella are entirely asymptomatic and endocrinologically normal; however, some patients could have complaints of dizziness, vertigo, headache and visual alterations, and also could have some pituitary hormonal disorders.
