BACKGROUND: Ectopic pituitary adenomas (EPAs) are rare, and the suprasellar cistern seems to be the most common location. At this time, no detailed original classification, diagnosis, or treatment protocols for suprasellar pituitary adenomas (SPAs) have been described. CASE DESCRIPTION: A 19-year-old man showed visual disturbances and lack of libido for 3 years, he suffered a sharp decline in vision with only light perception in the last week. Magnetic resonance imaging scans revealed a large suprasellar cystic lesion with a normal pituitary in the sella turcica...

BACKGROUND: Currently, there is no prioritization scale available to distinguish those patients with pituitary tumors who require urgent surgical intervention from those who are candidates for elective treatment. OBJECTIVE: To develop a classification system that can help primary care physicians, endocrinologists, neurosurgeons, ancillary support staff, and hospital administrators identify high-priority surgical candidates. METHODS: An expert international panel of clinicians consisting of endocrinologists and neurosurgeons who are involved in the diagnosis and management of sellar disease was convened...

During the last two decades endoscopic skull base surgery observed a continuous technical and technological development 3D endoscopy and ultra High Definition (HD) endoscopy have provided great advances in terms of visualisation and spatial resolution. Ultra-high definition (UHD) 4K systems, recently introduced in the clinical practice, will shape next steps forward especially in skull base surgery field. Patients were operated on through transnasal transsphenoidal endoscopic approaches performed using Olympus NBI 4K UHD endoscope with a 4 mm 0° Ultra Telescope, 300 W xenon lamp (CLV-S400) predisposed for narrow band imaging (NBI) technology connected through a camera head to a high-quality control unit (OTV-S400 - VISERA 4K UHD) (Olympus Corporation, Tokyo, Japan)...

Rubinstein-Taybi Syndrome (RSTS) is an autosomal dominant disorder that is classically characterized by prenatal and postnatal growth restriction, microcephaly, dysmorphic craniofacial features, broad thumbs and toes, and intellectual disability. We describe the first reported case of a pituitary macroadenoma associated with RSTS. A 39-year-old Caucasian female with a past medical history of RSTS diagnosed at age two was found to have a gadolinium-enhancing pituitary mass on magnetic resonance imaging (MRI) of the brain three years ago during workup for migraine-like headaches...

We report a case of granulomatous hypophysitis caused by Rathke's cleft cyst (RCC) mimicking a growth hormone (GH)-secreting pituitary adenoma. Neuroradiological and endocrinological evaluations showed abnormal findings consistent with acromegaly: Magnetic resonance imaging demonstrated a pituitary mass lesion, and GH and insulin-like growth factor I levels were markedly elevated, and GH levels were not suppressed in oral glucose tolerance test. Transsphenoidal surgery was performed, but no adenomatous tissue could be detected...

Space-demanding or destructive changes in the petrous bone are often challenging differential diagnosis. Cholesterol granulomas of the petrous apex can clinically present in a combination of hearing loss, vertigo, tinnitus, chronic cephalgia, impairment of facial nerve function, neuralgic pain of the nervus trigeminus, or manifest diplopia by the nerve palsy of the nervus abducens. CT-morphologically cholesterol granulomas appear as soft-tissue density masses, which may display a discrete rim after intravenous administration of a contrast agent...

SUMMARY: A 54-year-old man had gastrinoma, parathyroid hyperplasia and pituitary tumor. His family history indicated that he might have multiple endocrine neoplasia type 1 (MEN1). MEN1 gene analysis revealed a heterozygous germline mutation (Gly156Arg). Therefore, we diagnosed him with MEN1. Endocrinological tests revealed that his serum prolactin (PRL) and plasma adrenocorticotropic hormone (ACTH) levels were elevated to 1699 ng/mL and 125 pg/mL respectively. Immunohistochemical analysis of the resected pancreatic tumors revealed that the tumors did not express ACTH...

OBJECTIVE Parasellar tumors that extend far laterally beyond the internal carotid artery or that are fibrous and adhere firmly to critical structures are difficult to remove totally via the endoscopic transsphenoidal approach alone. In such cases, a combined transsphenoidal-transcranial approach is effective to achieve maximal resection in a single stage. In this paper, a new minimally invasive surgical technique for complicated parasellar lesions, a fully endoscopic combined transsphenoidal-supraorbital keyhole approach, is presented...

Here we review the technical aspects of our experience with the neuroendoscopic bilateral nostril (binostril) transsphenoidal approach for pituitary adenomas. A total of 42 patients were treated in our hospital from September 2013 to December 2015. Total tumor resection was completed in 31 cases, nearly full resection was achieved in 9 cases, and partial resection was achieved in 2 cases. In most cases clinical symptoms were relieved after surgery. These included 18/22 cases with visual field and vision disorders; 19/25 cases with headaches; 11/15 cases where high baseline PRL returned to normal levels; 6/7 cases where elevated blood GH returned to normal levels; and 2/3 cases where elevated blood ACTH returned to normal levels after surgery...

The classical term "pituitary apoplexy" (PA) describes a clinical syndrome usually characterized by abrupt onset of headache accompanied by neurologic and/or endocrinologic deterioration due to sudden expansion of a mass within the sella turcica as a result of hemorrhage or infarction within a pituitary tumor and adjacent pituitary gland. PA is a medical emergency and a difficult diagnosis to establish. Thus this article reviews the presenting symptoms of PA patients to help clinicians recognize or at least suspect this critical condition early on...
