Pituitary Tumors: Symptoms, Diagnosis, and Treatment Options

Pituitary tumor

Hello Dr.
Ding: I underwent an MRI examination...
In September, the results indicated a pituitary tumor (the January examination showed pituitary hyperplasia).
The neurologist mentioned that there is slight pressure on the optic nerve and the vomiting center.
My prolactin level is approximately 88.
He referred me to a neurosurgeon who told me, "Having a tumor at 17 years old is not a big deal...
stress can also cause tumors." He advised me to wait until after menopause to return for a follow-up.
However, I frequently experience dizziness, headaches, nausea, and weakness in my hands, which somewhat affects my daily life.
I'm unsure of what to do and hope the doctor can provide me with some advice.
Thank you ^^ PS.
My mother also has a brain tumor (in the same location)...
but she has already undergone surgery.
Brain tumors should not be hereditary...
Could it be that my mother and I have similar constitutions that led to this?

If your prolactin level is only 88, it is possible that your pituitary tumor is not very large.
However, without seeing your MRI, I cannot provide a well-informed recommendation.
Symptoms such as dizziness, headaches, nausea, and weakness in the hands are not always necessarily caused by this condition.
Additionally, based on your message, it seems that your menstrual cycle has not stopped; if that is the case, we must also consider whether your pituitary tumor is truly affecting you.
Furthermore, I am unaware if you are experiencing lactation, which limits my ability to give you better advice.
I recommend that you gather all relevant information and seek another neurosurgeon for further recommendations.
Alternatively, you can visit my clinic for a more in-depth evaluation.
My clinic hours are Monday and Thursday mornings.

More Info

Understanding pituitary tumors is crucial for anyone experiencing symptoms or diagnosed with such a condition. Pituitary tumors, also known as pituitary adenomas, are abnormal growths that develop in the pituitary gland, a small gland located at the base of the brain. These tumors can be classified as functioning or non-functioning, depending on whether they produce hormones.

Symptoms
The symptoms of pituitary tumors can vary widely based on the size of the tumor and whether it is secreting hormones. Common symptoms include:
1. Headaches: Often due to pressure on surrounding structures.

2. Vision Problems: Tumors can press on the optic nerves, leading to vision loss or double vision.

3. Hormonal Imbalances: Depending on the type of hormone produced, symptoms can include irregular menstrual cycles, infertility, weight gain, or changes in libido.

4. Nausea and Vomiting: This can occur if the tumor exerts pressure on the brain.

5. Fatigue and Weakness: These can be general symptoms related to hormonal changes.

In your case, the symptoms of dizziness, headaches, nausea, and weakness are concerning and should not be ignored. These symptoms can significantly impact your quality of life and may indicate that the tumor is affecting surrounding brain structures.

Diagnosis
MRI is the gold standard for diagnosing pituitary tumors. It provides detailed images of the pituitary gland and surrounding tissues, allowing doctors to assess the size and extent of the tumor. Blood tests to measure hormone levels, such as prolactin, are also essential for determining the type of tumor and its functional status.

Treatment Options
Treatment for pituitary tumors depends on several factors, including the tumor's size, type, and whether it is causing symptoms. Common treatment options include:
1. Observation: If the tumor is small and not causing significant symptoms, doctors may recommend regular monitoring with MRI scans and hormone level checks.

2. Medications: For functioning tumors, medications can help control hormone production. For example, dopamine agonists are often used for prolactin-secreting tumors.

3. Surgery: If the tumor is large, causing significant symptoms, or not responding to medication, surgical removal may be necessary. Transsphenoidal surgery, where the tumor is accessed through the nasal cavity, is a common approach.

4. Radiation Therapy: This may be used if surgery is not an option or if the tumor recurs after surgery.

Genetic Considerations
Regarding your concern about hereditary factors, while most pituitary tumors are sporadic and not inherited, certain genetic conditions can increase the risk of developing these tumors. If your mother has a history of pituitary tumors, it may be worth discussing this with a genetic counselor or your healthcare provider to understand any potential hereditary risks.

Next Steps
Given your symptoms and the impact they have on your daily life, it is essential to communicate these concerns to your healthcare provider. You may benefit from a more proactive approach, such as seeking a second opinion or discussing the possibility of surgical intervention, especially if your symptoms worsen or do not improve.

In conclusion, pituitary tumors can be complex, and their management often requires a multidisciplinary approach. Regular follow-ups with your healthcare team, including neurologists and endocrinologists, are crucial for monitoring your condition and ensuring the best possible outcomes.
