Abstract
BACKGROUND: Head trauma is a rare inciting factor of pituitary apoplexy (PA); however, there is a clear temporal relationship between trauma and apoplexy, and this is the first reported case of PA after an assault.
CASE DESCRIPTION: We present a rare case of a 63-year-old man who developed PA after sustaining a closed head injury from assault with a metal pole. The patient had a known pituitary tumor for which he had previously declined surgical resection. On initial computed tomography scan, there was no traumatic intracerebral hemorrhage or subarachnoid hemorrhage. There was sellar expansion but no obvious sellar hemorrhage. Within 48 hours of admission, the patient was presumed septic after developing altered mental status, fevers, hypotension, and tachycardia. Magnetic resonance imaging of the brain with and without gadolinium revealed a poorly enhancing, necrotic, and hemorrhagic pituitary mass, consistent with pituitary tumor apoplexy. After administration of intravenous glucocorticoids, the patient underwent emergent endoscopic transsphenoidal resection of the pituitary tumor apoplexy. Postoperatively, the patient had neurologic improvement with stable vision.
CONCLUSIONS: Early and accurate diagnosis is important to allow for timely neurosurgical intervention. Symptoms of fever, hypotension, and tachycardia in a patient with a known sellar mass should raise the suspicion of hypocortisolemia from pituitary tumor apoplexy.
