Diagnosing a Pituitary Tumor: Tests and What Comes Next

Three Pillars of the Workup

A pituitary tumor is diagnosed by combining imaging, hormones, and vision testing — each answers a different question.

1. Pituitary MRI

A pituitary MRI shows the tumor, its size, and whether it touches the optic nerves. It is the single most important imaging test.

2. Hormone Blood Tests

A panel of hormone tests shows whether the tumor is making too much of a hormone and whether the rest of the gland is working normally.

3. Visual-Field Testing

If the tumor is near the optic nerves, a visual-field test measures your side vision and provides a baseline.

What Happens After a Tumor Is Found

Once the picture is complete, we review whether the tumor needs treatment and, if so, whether that is medication, surgery, or monitoring. Many tumors do not need surgery at all.
