Surgical treatment of pituitary apoplexy in association with hemispheric infarction.

We report a patient with pituitary apoplexy in whom cerebral infarction developed, possibly secondary to vasospasm. Pituitary apoplexy is a clinical syndrome caused by acute hemorrhage or infarction of the pituitary gland. Our patient's clinical symptoms and radiographic findings greatly improved after surgical resection of the apoplectic pituitary gland. An extensive literature review was performed, including all previously reported cases of pituitary apoplexy leading to cerebral infarction. The clinical features, pathophysiological mechanisms, management and outcome of cerebral infarction following pituitary apoplexy are discussed. We show that cerebral infarction following pituitary apoplexy is associated with much poor prognosis. Early surgical decompression of the tumor and hemisphere should be performed in patients with severe or progressive neurological deficits, however, those with less severe presentations may be treated conservatively or with delayed elective surgery.
