We present the first Asian case of a 77-year-old man who developed pituitary apoplexy (PA) soon after gonadotropin-releasing hormone agonist (GnRHa) (leuprorelin) injection to treat prostate cancer. Headache, ophthalmoplegia, visual field deficit, nausea, and vomiting are the typical characteristics of pituitary apoplexy. Though the occurrence rate is rare, the consequence of this condition can...
BACKGROUND Pituitary adenoma may present with neuro-ophthalmic manifestations and, typically, rapid tumor expansion is the result of apoplexy. Herein, we present the first case of an isolated sixth cranial nerve palsy as initial feature of a rapidly expanding ACTH positive silent tumor without apoplexy. CASE PRESENTATION A 44 year old female with a history of sarcoidosis presented with an iso...
Pituitary apoplexy is a clinical syndrome with unknown pathogenesis. Therefore, identifying the underlying mechanisms is of high clinical relevance. Tumor necrosis factor alpha (TNF-α) is a critical cytokine mediating various hemorrhagic events, but little is known about its involvement in pituitary apoplexy. Here we show that TNF-α may be an important regulator of hemorrhagic transformation in...
THE common presentation of pituitary tumours is with the gradual onset of visual impairment, often in patients in whom there is evidence of endocrine abnormality. Infarction or haemorrhage of a pituitary tumour which has hitherto been clinically silent can result in the dramatic syndrome known as pituitary apoplexy. The onset is characterized by severe headache, vomiting, pyrexia, drowsiness le...
BACKGROUND Pituitary macroadenoma is a common benign tumor that usually presents with visual field defects or hormonal abnormalities. Cerebral infarction can be a complication of a large pituitary adenoma. We report a rare case of bilateral anterior cerebral arteries infarcts by a large pituitary macroadenoma with apoplexy. CASE REPORT A 48-year-old male patient presented with altered conscious...
A case of Eaton-Lambert syndrome associated with pituitary apoplexy is presented. It is thought to be the first reported case. The clinical features, electrophysiological findings and effects and side effects of therapeutic drugs are noted. Endocrinological dysfunctions are discussed in relation to pituitary disorder.
We report a case of pituitary apoplexy resulting in right internal carotid artery occlusion accompanied by hemiplegia and lethargy. A 43-yr-old man presented with a sudden onset of severe headache, visual disturbance and left hemiplegia. Investigations revealed a nodular mass, located in the sella and suprasellar portion and accompanied by compression of the optic chiasm. The mass compressed th...
