Thank you for posting your query.

The MRI reports suggest a small benign tumor (not cancer) of the pituitary gland. This is not something to worry about and it does not require any surgery.

You should consult an endocrinologist (the doctor who specialises in hormone treatment). He would ask for a pituitary hormone profile test (as pituitary gland produces a few hormones). In microadenoma, there may be an increase in some hormones such as prolactin or growth hormone.

If prolactin level is high, medications such as bromocriptine or cabergoline may be used for treatment. In due course of time, pituitary gland size returns to normal.

An eye check up may also be done, as some nerves which are required for vision may get occasionally compressed with pituitary gland tumors.

I hope it helps. Please get back if you have any more queries.

Thank you for your warm response.

Few things which i want to get clear from you are:

1) Is it a neuro problem or endocrinological problem.
2) how long is this treatment and what can be the dosage of medicine.
3) is it 100% curable if Yes Is there any chance it will happen again in future.
4) What are the side effects of the treatment/medicine.

Thank you

Thank you for getting back, and below are the replies.

1. It is a neuro problem, as it involves problem in pituitary gland, a part of brain. A neuro doctor is involved in planning the treatment. A big tumor would require surgery done by neurosurgeon. However, in this case, as the tumor is small, medicines are enough.

2. The medicines are to suppress the hormones released from pituitary gland. This is best done under the supervision of endocrinologist.

3. The dose of medicine is decided n the basis of hormone profile report. Duration also depends on that. Usual treatment may go on for at least 1-2 years.

4. It is usually 100% curable, however, it may recur in a small percentage of people.

5. Medicines are safe, and there are no significant side effects.

Best wishes,
Dr Sudhir Kumar MD DM (Neurology)

I was recently told I have empty sella found on a MRI. Also found low testosterone. I feel very fatiuged and can't handle stress very well. This has been going on for 3 to 5 years. Could I have a pituitary problem affecting other hormones such as cortisol. Thanks Jim C.

I was diagnosed with hypopituitarism including central insipidus diabetes, growth hormone deficiency, low testosterone , septo optic dysplasia.and legal blindness and also delayed puberty. My pituitary gland with mri showed to be very tiny. I dont know if this is a related issue or not but I've always had a very poor sense of smell, some things i cant smell at all some i cant distinguish, so my question is is this related to the pituitary condition or is it something else, in either case what could it be.

So here's the question, I have been fatigued for over 2 yrs. My son was born with panhypopituitarism. @ 6 wks old he went into adrenal shock/crisis. Since that day, I have walked on eggshells, the fatigue stared 6 months after he was born. I also have other symptoms, night sweats, confusion, muscle weakness, cold hand & feet, inability to focus, weight gain, low blood pressure, red dots on my skin (like tiny spots of blood) frequent skin infections, that heal SLOWLY, breast lactating, abdominal discomfort & constipation. All of which I NEVER had before, but my doctor says I am just overwhelmed/depressed. Is he right?
