On examination, there was a complete oculomotor nerve palsy. January Pages An unruptured posterior communicating artery aneurysm was suspected and urgent cerebral angiography performed. The presence of mixed oculomotor palsies or bilateral ophthalmoplegia and an afferent papillary defect or chiasmal patterns of field loss help to differentiate apoplexy from aneurismal subarachnoid haemorrhage.

Cerebral ischemia due to pituitary apoplexy is very rare. Optochiasmatic syndrome from adhesive arachnoiditis with coesxisting hypophyseal adenoma: A patient with sudden onset of ptosis, particularlywith a complete oculomotor palsy is most likely to be diagnosed apoplejka a posterior communicating artery aneurysm and not a pituitary tumour.
Patients may present with acute ptosis. South Med J ; Pituitary adenomas complicating cardiac surgery: Headache is common and may be the only presenting symptom. Two cases of pituitary tumour presenting with ptosis are reported. Subsequent magnetic resonance apkplejia MRA also revealed narrowing of the left carotid siphon and images of the brain showed a pituitary tumour of inhomogenous but mainly high signal intensity on T1 weighted images T1WI and iso-intensity on T2 weighted images T2WIin keeping with a haemorrhagic tumour.
The previous medical history was noncontributory. Pituitary apoplexy after subtotal thyroidectomy in an acromegalic patient with a large goiter. They are more common in women than men, usually presenting with endocrine ;ituitaria. Continuing navigation will be considered as acceptance of this use.

Pituitary adenoma is the most common tumour of the sella turcica and suprasellar cistern. At surgery, a haemorrhagicpituitary adenoma was found.
Cerebral infarction after pituitary apoplexy: Treatment consists in urgent sellar decompression by transsphenoidal surgery and substitute therapy with steroids. The sudden increase in pressure of the sella turcica’s contents results in a clinical syndrome characterized by headache which can be “thunderclap headache”visual disturbances and hypopituitarism. The following patients remind us that pituitary apoplexy is an uncommon but important associated finding in acute unilateral ptosis. Histology confirmed a pituitary adenoma with extensive areas of haemorrhage and necrosis, consistent with apoplexy.
On examination, he was found to have partial left oculomotor there was pupillary sparing and trochlear nerve palsies. Essentials of Neuroimaging 2nd ed. Oculomotor nerve palsies generally develop as the end stage of an expanding tumour, combined with visual loss.
