MRI scans

Classification
There are two types of empty sella syndrome: primary and secondary. Primary empty sella syndrome occurs when a small anatomical defect above the pituitary gland increases pressure in the sella turcica and causes the gland to flatten out along the interior walls of the sella turcica cavity. Primary empty sella syndrome is associated with obesity and increase in intracranial pressure in women. In most cases, especially in people with primary empty sella syndrome, there are no symptoms and it does not affect life expectancy or health. Some researchers have estimated that less than 1% of affected people ever develop symptoms of the condition. Secondary empty sella syndrome is the result of the pituitary gland regressing within the cavity after an injury, surgery, or radiation therapy. Individuals with secondary empty sella syndrome due to destruction of the pituitary gland have symptoms that reflect the loss of pituitary functions, such as intolerance to stress and infection. Differential diagnosis
The major differential to consider in empty sella syndrome is intracranial hypertension, of both unknown and secondary causes, and an epidermoid cyst, which can mimic cerebrospinal fluid due to its low density on CT scans, although MRI can usually distinguish the latter diagnosis. Treatment
In terms of management, unless the syndrome results in other medical problems, treatment for endocrine dysfunction associated with pituitary malfunction is symptomatic and thus supportive; however, surgery may be needed in some cases. References
