introduction: the co-existence of pituitary adenoma and meningioma is extremely rare. it is even rarer in patients with no previous known risk factors for either tumour. here, we present a case of synchronous non-functioning pituitary adenoma with suprasellar and olfactory groove meningiomas in a patient without previous irradiation. methods: the tumours were diagnosed on mri in the 65-year-old...

Cavernous segment internal carotid artery (CSICA) injury during endoscopic transsphenoidal surgery for pituitary tumor is rare but fatal. The aim of this study is to investigate anatomical relationship between pituitary macroadenoma and corresponding CSICA using quantitative means with a sense to improve safety of surgery.In this retrospective study, a total of 98 patients with nonfunctioning p...

background: nowadays, drug and observation are advised to patients with lymphocytic hypophysitis and in some cases with nonfunctioning pituitary macoadenoma, instead of surgery. case presentation: in this article, we report a woman with nonfunctional pituitary macroadenoma and panhypopitutarism and negative criteria for lymphocytic hypophysitis associated with increased liver enzymes. after thr...

Among pituitary disorders having mass effect of the pituitary gland, nonfunctioning pituitary macroadenoma and lymphocytic hypophysitis are difficult to differentiate without histological examination. In order to efficiently distinguish lymphocytic hypophysitis and pituitary tumors, we studied the presence of autoantibodies against prohormone-processing enzymes, prohormone convertase (PC) 1/3, ...

The pituitary gonadotropic adenoma is an developed́ in the cells of anterior pituitary. It can be secreting releasing excess blood and urine; products its secretion are gonadostimulines (F.S.H. L.H.) or non-secreting this case only histo- cytochemical analysis will able to allow identification. We report two cases macroadenoma with LH-FSH immunostaining. Pituitary magnetic resonance imaging reve...

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...

The Mayer-Rokitansky-Küstner-Hauser (MRKH) syndrome is characterized by congenital aplasia of the uterus and upper part (2/3) of the vagina in women showing normal development of secondary sexual characteristics with a normal 46, XX karyotype. We report a case of a 30-year-old woman who presented with complaints of headache. Pituitary macroadenoma and MRKH syndrome were diagnosed. To the best o...

A 45-year-old woman, with a history of asymmetric facial flushing, was presented to the Endocrinology Unit after pituitary macroadenoma removal. After other pathological entities had been ruled out, she was diagnosed with harlequin syndrome following a lesion of the postganglionic sympathetic fibers during transsphenoidal pituitary macroadenoma surgery. We herein report the first case of harleq...

Pituitary adenoma is a benign neoplasm of pituitary gland. adenoma, particularly macroadenoma,may produce mass effect symptoms by compressing surrounding tissues. Due to function as aneuroendocrine organ, may also cause multiple endocrine disturbances. The authors reportthe case 39-year-old male patient presenting with chronic headache and history seizure. MRI imagingrevealed macroadenoma optic...
