Successful Emergency Endovascular Treatment of Cavernous Internal Carotid Artery Stenosis Due to Compression by a Hemorrhagic Pituitary Tumor

Ischemic stroke associated with pituitary apoplexy is an extremely rare but devastating complication. Arterial stenosis or occlusion due to direct compression secondary to acute expansion of the hemorrhagic pituitary adenoma may induce ischemic stroke. In case of presentation of diffusion-perfusion or diffusion-clinical mismatch, urgent tumor resection to decompress the involved arteries should be performed to salvage ischemic penumbra. If emergent surgery is not possible, other therapeutic options are needed to prevent the progression of cerebral ischemia. Herein, we report the case of successful revascularization achieved in a patient with ischemic stroke who underwent balloon angioplasty and stent placement for the non-atherosclerotic steno-occlusion of intracranial internal carotid artery due to pituitary apoplexy.
