Abstract
Pituitary Apoplexy (PA) is defined as a clinical syndrome comprising headache, visual deficits and altered sensorium, which can result from haemorrhage or infarction of the pituitary gland. Acute ischaemic stroke following PA is very rare. We are presenting a 35-year-old young otherwise healthy lady who presented with neuro ophthalmological and vascular symptoms on a background of PA. Imaging revealed a pituitary macro adenoma with parasellar extension with internal bleed. Cerebral angiography revealed that the mass compressed the bilateral cavernous sinuses (left more than right), resulting in obliteration of the cavernous portion of the left Internal Carotid Artery (ICA). She was treated with steroids and surgical debulking of the tumour through trans-sphenoidal approach and postoperative imaging showed recanalization of the ICA with reduction of the tumour size. The histopathological diagnosis was consistent with pituitary macro adenoma. Patient improved in level of sensorium, eye movement and the patient showed almost full recovery after the operation. PA resulting in ICA occlusion is very rare. Early intervention is required for reducing mortality and morbidity and to improve quality of life.
