Pituitary apoplexy presenting with an orbital bruit.
Pituitary apoplexy is a sight-threatening syndrome in which a pituitary adenoma undergoes sudden enlargement as a result of haemorrhage, infarction or both. Classic features of the syndrome include sudden severe headaches, reduced consciousness, visual impairment, ophthalmoplegia and/or endocrinological disturbance. Pituitary apoplexy has been reported following cardiac bypass surgery. The case is reported of a 68-year-old man who presented with left external and internal ophthalmoplegia, complete ptosis, mild chemosis, reduced vision, and an orbital bruit following coronary artery bypass grafting. Carotid angiography showed the left internal carotid artery to be bowed anteriorly and narrowed. Magnetic resonance imaging demonstrated features consistent with pituitary apoplexy. It is believed that an orbital bruit has not previously been reported in pituitary apoplexy.
