background: intracranial lesions of the pituitary gland are common pituitary adenomas, accounting for 6-10% of all symptomatic intracranial tumors. in this retrospective study, the clinicopathologic features and survival rate of pituitary adenomas were evaluated. methods: the present retrospective study was conducted on 83 patients with pituitary adenomas, referring to radiation oncology depart...
Routine classification of pituitary adenomas is not appropriate for diagnosis of adenoma type and in some cases there is inconcordance between clinical presentation and histological type of adenoma. The aim of this study was to determine the type of adenoma secretion based on immunohistochemical staining. 102 paraffin blocked specimens of pituitary adenoma were stained with hormone ...
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...

background & aim: we described the presentation, management and subsequent treatment outcomes of children and adolescents diagnosed with a pituitary adenoma in a joint neuroendocrine setting followed up by a single service as well as assessing long-term outcomes in terms of endocrine status and neurology symptoms. methods & materials/patients: a total of 21 participants with histologically veri...
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...
purpose: to study early treatment outcomes and complications of gamma knife radiosurgery (gkrs) in patients with functional and nonfunctional adenomas. methods: one hundred patients with a pituitary adenoma who were treated between 2011 and 2014 at iran gamma knife center were studied. the patients were followed up at least 2 years. radiosurgery was performed using the leksell gamma unit. the m...
Background & Aim: Pituitary adenomas are a part of a dissimilar group of benign neoplasms. The development of endoscopic techniques for surgery of paranasal sinuses has increased the opportunity for an endoscopic approach with regard to the pituitary gland. Minimally invasive endoscopic pituitary surgery, in turn, permits a more thorough tumor resection and fewer associated surgical complicatio...
Background and Objective: Pituitary adenoma (PA) is one of the most common intracranial tumors. In recent years, some research has been done on patients with PA. Given the lack of similar research in Iran, this study was conducted to assess the demographic characteristics and the quality of life among Iranian patients with PA. Materials and Methods: This study was a cross- sectional- de...
Background and Importance: The coexistence of pituitary adenoma and another type of brain tumor is a very rare clinical scenario. Even though such a presentation can be an incidental event but the possible pathogenesis of coexistence of different lesions in the sella and suprasellar region has not yet been elucidated. Case Presentation: Two cases of concomitant sellar and suprasellar region ...
