MRI The diagnosis of<unk> , done via examination (and test), may be linked to early onset of puberty, growth hormone deficiency, or pituitary gland dysfunction (at an early age). Additionally there is: ::::::::*CT scan ::::::::*MRI scans Classification There are two types of<unk> : primary and secondary. * Primary<unk>  occurs when a small anatomical defect above the pituitary gland increases pressure in the<unk>  turcica and causes the gland to flatten out along the interior walls of the<unk>  turcica cavity. Primary<unk>  is associated with obesity and increase in intracranial pressure in women. In most cases, especially in people with primary<unk> , 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<unk>  is the result of the pituitary gland regressing within the cavity after an injury, surgery, or radiation therapy. Individuals with secondary<unk>  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<unk>  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.
