Pituitary apoplexy often manifests with a severe headache and is often caused by bleeding in a pituitary adenoma, which is common and often undiagnosed. The pituitary gland is damaged when the tumour suddenly enlarges due to bleeding. Bleeding into the pituitary can block blood supply to the pituitary gland. The larger the tumour, the higher the risk of a future pituitary apoplexy. Since only few cases have been reported, the SARS-CoV-2 vaccine is unlikely to cause pituitary apoplexy. Patients with new-type headache require neurological evaluation and may require cerebral imaging to rule out bleeding, ischemia, venous sinus thrombosis, meningitis, encephalitis, pituitary apoplexy, reversible cerebral vasoconstriction syndrome, dissection, or migraine.
