"Higher grades are termed complete/total empty sella and lower grades are termed partially/partial empty sella. The border between these two categories is commonly defined in the endocrinology literature in the following manner 6,15,16:"

"Previously, the term empty sella syndrome was used to denote patients with headaches and visual disturbances. It is now thought that many of these patients have idiopathic intracranial hypertension and that the empty sella is actually secondary to elevated CSF pressures."

"The finding of pituitary gland height loss and CSF protrusion into the sella turcica occurs in gradations (see pituitary grading), resulting in variability in descriptive terminology. At the less restrictive end of the spectrum, some authors use empty sella to refer to any degree of pituitary height loss/concavity (at least grade II) 11. More reasonable authors define empty sella as at least 33% pituitary height loss (grade III) 14. Most strictly, some authors reserve the term empty sella for when there is essentially no visible pituitary tissue and the fossa is at least a little enlarged (grade V)."
"complete/total empty sella: >50% of the sella filled with CSF; pituitary thickness ≤2 mm"
"partial empty sella:"
"It is difficult to determine which patients, if any, would fit in the primary category, as it is increasingly believed that these patients represent either patients with elevated CSF pressures who are nonetheless asymptomatic or patients who have had a previously undiagnosed condition (e.g. idiopathic intracranial hypertension 3, lymphocytic hypophysitis 6, Sheehan syndrome 9, etc.)."
