A pituitary adenoma is a usually benign tumor that develops in the pituitary gland, located at the base of the brain. The pituitary gland plays a central role in the production and secretion of hormones in the body. Therefore, an adenoma that develops in this gland can create imbalances in many organs of the body. Prof. Dr. Ömür Günaldı emphasizes that even small pituitary adenomas can lead to serious hormonal disorders and that early diagnosis is therefore extremely important.
The pituitary gland is considered the “control center of the body.” It regulates the thyroid, adrenal glands, sex hormones, and growth hormones. Adenomas in this gland may cause hormonal excess or deficiency, leading to various systemic symptoms.
Prof. Dr. Ömür Günaldı notes that although most pituitary adenomas are benign, they may cause effects such as vision loss, headaches, and permanent hormonal disorders in some cases.
Hormone-Secreting (Functional) Adenomas
These adenomas produce excessive hormones and manifest with hormonal imbalances.
Non-Functioning Adenomas
These do not produce hormones but may grow and put pressure on surrounding structures. They may cause vision loss, especially by pressing on the optic nerve.
Prof. Dr. Ömür Günaldı states that whether an adenoma produces hormones completely changes the diagnosis and treatment plan; therefore, detailed hormonal analysis is essential.
The exact cause of pituitary adenomas is not fully known, but several factors are believed to contribute:
Prof. Dr. Ömür Günaldı emphasizes that while genetic factors play an important role in some patients, environmental factors should not be overlooked.
Headache
This is the most common symptom. As the adenoma grows in the pituitary region, it presses on surrounding tissues and causes intense pain, especially in the forehead region.
Vision Problems
As the tumor grows, it presses on the optic nerve. Visual field narrowing, blurriness, or double vision may develop.
Hormonal Imbalances
Different symptoms appear depending on the hormone produced by the adenoma:
Fatigue and Weakness
Energy deficiency and fatigue are common due to hormone deficiencies.
Prof. Dr. Ömür Günaldı emphasizes that symptoms vary from person to person and that individuals experiencing headaches or vision loss should have their pituitary region examined.
Hormone Tests
Blood levels of prolactin, growth hormone, cortisol, thyroid hormones, and sex hormones are measured.
Imaging Methods
Magnetic Resonance Imaging (MRI) is the gold standard for identifying the location and size of the tumor in the pituitary region.
Eye Examination
The level of pressure on the optic nerve is evaluated with visual field tests.
Prof. Dr. Ömür Günaldı states that the most important step in diagnosing a pituitary adenoma is the combined analysis of hormonal evaluations and imaging results.
Medication
Some adenomas can be controlled with medication. For example, in prolactinomas, hormone production can be suppressed with dopamine agonists.
Surgical Treatment
Pituitary surgery is performed in adenomas that do not respond to medication, are large in size, or put pressure on the optic nerve.
Prof. Dr. Ömür Günaldı uses the endoscopic transsphenoidal surgical technique as one of the safest and most effective methods. In this technique, the tumor is removed through the nasal passage without harming the brain tissue.
Radiotherapy
If residual tumor tissue remains after surgery, radiotherapy is applied to prevent tumor cell growth.
Hormone Therapy
Some pituitary functions may weaken after surgery. In such cases, deficient hormones are supplemented from the outside.
Prof. Dr. Ömür Günaldı emphasizes that the treatment plan must be personalized and that different strategies are applied according to the type of tumor and hormonal profile in each patient.
The most commonly preferred method in pituitary adenoma surgery is endoscopic transsphenoidal surgery. In this procedure, the surgeon enters through the nose, reaches the pituitary region through the sphenoid sinus, and removes the tumor using microsurgical instruments.
Prof. Dr. Ömür Günaldı lists the advantages of this method
Patients can stand up within 2–3 days after surgery and are usually discharged within a week.
Cerebrospinal Fluid Leak
A small opening in the membrane during surgery may lead to fluid leakage.
Infection (Meningitis)
This risk is quite low with sterile surgical techniques.
Hormone Deficiencies
Production of some hormones may decrease after surgery. Balance is restored with medication.
Vision Problems
Temporary blurriness or double vision may rarely occur.
Prof. Dr. Ömür Günaldı states that most of these complications are temporary and can be controlled with early diagnosis and correct intervention.
Prof. Dr. Ömür Günaldı emphasizes that the first year after treatment is the most critical period and that regular follow-up should not be neglected.
In tumors pressing on the optic nerve, surgical removal of the pressure rapidly restores vision. However, in cases of long-term nerve damage, full recovery may not always be possible.
Prof. Dr. Ömür Günaldı particularly stresses that surgical decisions should not be delayed in patients experiencing vision loss.
Pregnancy planning in women with pituitary adenoma requires careful management.
Pregnancy may be risky if hormonal imbalances are not treated.
Prof. Dr. Ömür Günaldı recommends completing surgical or medical treatment before considering pregnancy in women planning to conceive.
Prof. Dr. Ömür Günaldı notes that surgical procedures performed by experienced hands reduce complications and provide long-term recovery.
Advanced endoscopic systems, intraoperative MRI, and neuronavigation devices increase surgical accuracy.
These technologies allow surgeons to check whether the tumor has been completely removed during the operation.
Prof. Dr. Ömür Günaldı emphasizes that technological advancements significantly improve patient safety, especially in complex pituitary cases.
The cost of pituitary adenoma treatment varies depending on the type and size of the tumor, the method used, the duration of hospital stay, and additional treatments required.
Prof. Dr. Ömür Günaldı individualizes the treatment plan according to the patient’s needs and economic conditions.
Prof. Dr. Ömür Günaldı applies long-term follow-up programs to help patients maintain their quality of life after surgery.
Hormonal imbalances may lead to mood changes, anxiety, or depression.
Psychological support is an important part of treatment.
Prof. Dr. Ömür Günaldı believes that patients should be supported not only medically but also emotionally.
There is no definitive prevention method, but early diagnosis is possible.
Prof. Dr. Ömür Günaldı emphasizes that awareness and early diagnosis save lives.
A pituitary adenoma, although developing in a small gland, is a serious condition that affects the entire body. With early diagnosis, proper treatment, and regular follow-up, it can be completely controlled.
Thanks to endoscopic surgical techniques, patients can return to normal life in a short time.
Prof. Dr. Ömür Günaldı provides safe, effective, and long-lasting solutions by combining modern technology and scientific approaches in the treatment of pituitary disorders.
Hormonal balance is the key to a healthy life, and early treatment of pituitary adenoma is the most important step in maintaining this balance.
