Pituitary apoplexy brain and the spinal cord; the sample is obtained with a needle that is passed under local anesthetic into the spine. In pituitary apoplexy the results are typically normal, although abnormalities may be detected if blood from the pituitary has entered the subarachnoid space. If there is remaining doubt about the possibility of subarachnoid hemorrhage (SAH), a magnetic resonance angiogram (MRI with a contrast agent) may be required to identify aneurysms of the brain blood vessels, the most common cause of SAH. Professional guidelines recommend that if pituitary apoplexy is suspected or confirmed, the minimal blood tests performed should include
