small nodular calcifications are present in the left tentorial incisura and left temporal region.

This is a patient forum, so we are not doctors. But a lot of us have tumors or issues with our brains or pituitary glands.
So what does the neurologist say about this? Is it causing pressure? Is there other testing that needs to be done? Is it treatable via surgery or by some other means?
What about your father? Is it causing problems for him? Sorry but I am full of questions.

What led you up to the point of having the CAT scan done?

Like Horse said, we are patients, but I don't think you gave the entire report.

It does sort of sound like the mass has been there a while - possibly - calcifications may indicate that.

There are two masses, but there a no indications of size.

Let us know what the doctors say about the lesions and his prognosis.
