An empty sella is believed to result from herniation of the arachnoid space into the pituitary fossa through a deficient diaphragm, found in 20% of the population 4,5.

Pediatr Endocrinol Rev. To detect the prevalence of empty sella in routine MRI brain study and to find associations with other diseases. 9. Online ahead of print. Definition Empty Sella Syndrome (ESS) is a disorder that involves the sella turcica , a bony structure at the base of the brain that surrounds and protects the pituitary gland. 1 doctor agrees. Often, empty sella syndrome is discovered incidentally on CT or MRI examination when individuals are being evaluated for other reasons. This is a 40 yr old female with spontaneous CSF leak. All my test have been normal borderline as my doctors explains. Not surprisingly, many patients who undergo brain imaging will have a partially empty sella. 3. Ekhzaimy AA, Mujammami M, Tharkar S, Alansary MA, Al Otaibi D. BMC Endocr Disord. An empty sella is believed to result from herniation of the arachnoid space into the pituitary fossa through a deficient diaphragm, found in 20% of the population 4,5. Flowchart showing selection of patients with empty sella for the study. Methods . 2013 May;200(5):1125-31. doi: 10.2214/AJR.12.9013. Figure 1a: MRI Brain (T2 FLAIR) showing Empty Sella Figure 1b: MRI Brian (T2 Saggital View) showing hyper intense signal intensity in the region of Sella Turcica suggestive of CSF filled Sella. Empty sella syndrome (ESS) may occur if you have an enlarged sella turcica. Herniation of the suprasellar visual system and third ventricle into empty sellae: morphologic and clinical considerations. See this image and copyright information in PMC. Herniations of suprasellar structures into the empty sella may occur, especially when the empty sella is secondary in origin, and most of these cases present with visual disturbances due to herniation of the optic chiasm 12. Either the gland has shrunk or has been crushed and flattened making it look like an empty sella on MRI scan. An Ophthalmologic evaluation revealed normal vision with mild bilateral optic disc edema (Figure 2a and 2b). The diagnosis of empty sella syndrome, done via examination (and test), may be linked to early onset of puberty, growth hormone deficiency, or pituitary gland dysfunction (at an early age). growth hormone deficiency 8) and hyperprolactinemia 7 are being recognized, although whether these conditions are secondary to the empty sella or rather both the empty sella and endocrinopathy represent the sequelae of previous disease is unclear. Saindane AM, Lim PP, Aiken A, Chen Z, Hudgins PA. Factors determining the clinical significance of an "empty" sella turcica. Recent results however challenged the pathophysiological importance of elevated intracranial pressure, demonstrating that instead hemodynamically significant stenosis of the venous sinuses could be the main culprit behind empty sella 13. People with empty sella syndrome may or may not have symptoms. Trying to assess the significance of an incidentally identified empty sella can be difficult, especially if no pertinent clinical notes are available. If thin section imaging is obtained the infundibulum may be seen coursing through the CSF-filled sella (see below). Various blood tests generally find one or mor… And it is not completely filled by the pituitary gland. Shore RN, Decherney AH, Stein KM et-al. 1975;25 (6): 565-9. The likelihood of it representing undiagnosed intracranial hypertension correlates with the patient's age and gender (middle age and female), orbital findings (flattened globes and optic nerve sheath prominence) and subcutaneous fat thickness as a marker of weight, although no cut-off measurements are available 11. those with an identifiable cause), such as prior tumors, radiotherapy, surgery, or hemorrhage, very similar in appearance, plus mass effect on the infundibulum, on high-resolution imaging, the margins of the cyst may be visible superiorly. The rest formed the baseline population. Clinical presentation, evaluation and case management of primary empty sella syndrome: a retrospective analysis of 10-year single-center patient data. Kaufman B, Tomsak RL, Kaufman BA, Arafah BU, Bellon EM, Selman WR, Modic MT. Recently, there have been studies documenting association of ES with hormonal and non-hormonal abnormalities.

T1WI sagittal post-contrast MRI demonstrating (a) normal pituitary gland and stalk (white arrow), (b) empty sella (white block arrow). Felix von Luschan. 13. From pituitary expansion to empty sella: disease progression in a mouse model of autoimmune hypophysitis. MRI images reveal a flattened thinned out pituitary gland and defect in the sellar floor on coronal CT scan images. This patient had a history of benign intracranial hypertension, with prominent empty sella. Autopsy studies confirm the high disease prevalence reported to be 5.5% to 20% of the general population. It is often identified coincidentally whilst carrying out investigations for other reasons. This is a bony structure at the base of the brain. But pituitary function is usually normal. Empty sella syndrome is diagnosed on computerised tomography or MRI scans of the pituitary area or brain. The patient is investigated as an outpatient.
