BackgroundPituitary apoplexy is an acute clinical syndrome caused by pituitary gland hemorrhage or infarction. Rarely, this clinical syndrome is associated with cerebral infarction secondary to compression of an internal carotid artery. We report an unusual case of pituitary apoplexy associated with a cerebral infarct with a large ischemic penumbra.Case DescriptionThe patient presented with headaches and visual disturbance and was found to have pituitary apoplexy. Findings of his neurologic examination showed he had rapidly deteriorated, with obtundation, ophthalmoplegia, and left hemiplegia. Computed tomography perfusion images revealed a right hemispheric infarct with a large ischemic penumbra. Emergent decompressive transsphenoidal resection was performed. The patient had dramatic neurologic recovery, and postoperative imaging revealed salvage of most of the previously identified penumbra.ConclusionsCerebral perfusion imaging is a useful diagnostic tool for identifying the subset of pituitary apoplexy patients that may benefit from emergent surgical intervention.Copyright © 2016 Elsevier Inc.
