What is an Empty Sella?

An empty sella is a medical condition that occurs when the sella turcica, a bony structure in the skull that surrounds the pituitary gland, becomes partially or completely filled with cerebrospinal fluid. This can result in a flattening of the pituitary gland against the walls of the sella turcica, giving the appearance of an “empty” sella when viewed on imaging studies.

While an empty sella itself may not cause any symptoms or health issues, it can sometimes be associated with hormonal imbalances or pituitary dysfunction. Patients with an empty sella may require monitoring and treatment to address any related complications, such as hormone deficiencies or excesses. Diagnosis of an empty sella is typically made through imaging studies, such as magnetic resonance imaging (MRI), and treatment may involve managing any underlying hormonal abnormalities.

An empty sella is a term used to describe a condition where the sella turcica, a bony structure in the skull that contains the pituitary gland, appears empty or partially filled. The sella turcica is located at the base of the brain, behind the nose, and plays a crucial role in housing and protecting the pituitary gland.

Understanding the Sell Turcica and the Pituitary Gland

The sella turcica, which means “Turkish saddle” in Latin, is named so because of its saddle-like shape. It is formed by a small depression in the sphenoid bone and is an essential anatomical structure.

The pituitary gland is a small gland situated within the sella turcica. It is often referred to as the “master gland” because it produces and regulates several hormones that control various bodily functions, including growth, metabolism, reproduction, and stress response.

Causes of an Empty Sella

An empty sella can be either primary or secondary. Primary empty sella syndrome occurs when the sella turcica is empty without any specific cause. On the other hand, secondary empty sella syndrome is associated with an underlying condition or medical procedure.

Primary Empty Sella Syndrome

Primary empty sella syndrome is believed to be a congenital abnormality that occurs during the development of the sella turcica. However, the exact cause is not well understood.

This condition is more common in women, especially those who have had multiple pregnancies or are obese. It may also be associated with conditions such as high blood pressure and increased intracranial pressure.

Secondary Empty Sella Syndrome

Secondary empty sella syndrome can be caused by various factors, including:

  • Head trauma: A severe blow to the head can damage the sella turcica, leading to an empty sella.
  • Pituitary surgery: Surgical procedures performed on the pituitary gland can sometimes result in an empty sella.
  • Radiation therapy: Radiation treatment for tumors in the head or neck region may affect the sella turcica.
  • Empty sella after pituitary adenoma treatment: In some cases, an empty sella can develop after the successful treatment of a pituitary adenoma (a noncancerous tumor of the pituitary gland).
  • Obesity: Excess weight can increase intra-abdominal pressure, which may lead to an empty sella.

Symptoms and Diagnosis

Most individuals with an empty sella are asymptomatic, meaning they experience no specific symptoms directly related to the condition. The empty sella is often discovered incidentally during imaging tests for unrelated conditions.

However, in some cases, individuals with an empty sella may experience symptoms associated with the underlying cause. For example, if the condition is secondary to a pituitary tumor, symptoms may include hormonal imbalances, vision problems, headaches, and fatigue.

Diagnosing an empty sella typically involves imaging studies, such as magnetic resonance imaging (MRI) or computerized tomography (CT) scans. These tests can visualize the sella turcica and determine if it appears empty or partially filled. Additional hormonal tests may also be carried out to assess pituitary function.

Treatment Options

In most cases, treatment for an empty sella is not necessary, especially if the individual is asymptomatic and has normal pituitary function. Regular monitoring through periodic imaging and hormonal tests may be recommended to ensure the condition does not worsen over time.

If an underlying condition, such as a pituitary adenoma, is identified, treatment will be focused on managing that specific condition. This may involve surgical removal of the tumor, radiation therapy, or medication to control hormone levels.

For individuals experiencing symptoms related to hormonal imbalances or other complications, hormone replacement therapy may be recommended to restore normal hormone levels and alleviate associated symptoms.

An empty sella may be a benign condition that often goes undiagnosed and requires no treatment. However, it is important to undergo proper medical evaluation if symptoms are present or an underlying condition is suspected. Regular follow-up and monitoring are crucial to ensure the empty sella does not cause any complications or affect pituitary function.

Remember, if you have any concerns or questions about an empty sella or any other medical condition, always consult with a healthcare professional to receive accurate diagnosis and appropriate treatment.

An empty sella refers to a condition in which the sella turcica, a bony structure in the skull that holds the pituitary gland, appears empty or partially filled with cerebrospinal fluid. This condition can be incidental and asymptomatic, or it can be associated with hormonal imbalances and other health issues. Further evaluation and management may be necessary to address any underlying conditions related to an empty sella.
