Pituitary Apoplexy with the Initial Presentations Similar to Trigeminal Autonomic Cephalalgia: A Case Report.

Pituitary apoplexy, defined by an acute ischemic or hemorrhagic event of the pituitary gland, can lead to neurological deficits. We present the case of a 43-year-old male who initially exhibited symptoms resembling trigeminal autonomic cephalalgia (TAC) as sudden-onset headache, ptosis, and autonomic symptoms. He later developed abducens nerve palsy and magnetic resonance imaging revealed a pituitary macroadenoma with intratumoral hemorrhage. Endocrine evaluation showed multiple hormonal deficiencies. The patient was diagnosed with pituitary apoplexy and referred for surgical intervention. This case highlights the importance of considering pituitary apoplexy in the differential diagnosis of TAC-like presentations and emphasizes the importance of neuroimaging in patients presenting atypical headaches. Early recognition and appropriate management are crucial for optimizing outcomes in this potentially life-threatening condition.
