Pituitary adenomas are rare in children, and often present with symptoms of headache, nausea or emesis, visual disturbance, or hormonal hypersecretion. With large tumors, mass effect from the lesion can lead to severe endocrinopathy and compression of intracranial neurovascular structures. In this case report, we describe an unusual presentation of an ischemic stroke in the territory of the right middle cerebral artery resulting from a prolactin-secreting macroadenoma. The patient's primary symptoms were headache, left facial droop, and left hemibody weakness. She was successfully managed with cabergoline, a dopamine agonist, with a reduction in the size of the tumor and normalization of serum prolactin levels. She remained clinically stable throughout her hospitalization, and was safely discharged without surgical intervention. In her recent 2-year follow-up, her tumor and prolactin levels were stable and she had dramatic improvements in her left-sided muscle strength.
