Background: Post-surgical empty sella is related to the removal of pituitary tumors either from the transcranial or transphenoidal route, rendering diaphragma sellae incompetent at the end of the procedure. This subsequently leads to herniation of the third ventricle and optic apparatus into the empty sella. Studies have shown that in 50% of the cases, individuals with primary and secondary empty sella syndrome have developed defects in the visual fields. Benign increased intracranial pressure, cerebrospinal rhinorrhea, papilledema, and abnormalities affecting visual acuity may also occur as a result of empty sella...

Pituitary apoplexy is a clinical syndrome characterized by acute headache, visual changes, and decreased consciousness occurring in association with hemorrhage or infarct of an existing pituitary adenoma. Surgical management involves tumor resection and decompression of surrounding structures including the optic apparatus. Vasospasm is a rare but potentially devastating complication of pituitary apoplexy. We present a case of pituitary apoplexy in a 28-year-old male treated with emergent endoscopic transsphenoidal resection...

BACKGROUND: Prolactinomas are typically treated nonsurgically with a dopamine agonist. Once the tumor shrinks, adjacent eloquent structures, such as the optic apparatus, can become skeletonized and herniate into the dilated parasellar space. CASE DESCRIPTION: A 48-year-old man with a prolactin-secreting macroadenoma treated with cabergoline presented with progressive bitemporal hemianopsia. Magnetic resonance imaging showed no recurrence of disease and a stretched optic chiasm herniating into an empty sella...

BACKGROUND: Postoperative visual recovery in patients with pituitary adenoma can be influenced by the duration of symptoms, age, and tumor volume. Diffusion tensor imaging (DTI) allows visualization of white matter structure along with quantitative information. The aims of our study were to predict the visual recovery process in the early and long-term periods and to define the parameters affecting the recovery course. METHODS: A total of 200 patients with pituitary macroadenomas underwent endoscopic transsphenoidal surgery between January 2009 and July 2016...

BACKGROUND: Primary meningeal melanocytoma is a benign lesion in the central nervous system derived from leptomeningeal melanocytes, most commonly growing in the posterior fossa and cervical spinal cord. The sellar primary meningeal melanocytoma (SPMM) is an exceptionally rare tumor. Here we report the ninth published case of an SPMM, and also discuss the problems of differential diagnosis and management of these tumors. CASE DESCRIPTION: The patient presented with visual impairment and irregular menstruation with no other symptoms...

Background: Despite the broad category of differentials for sellar region, most of them present with similar clinical signs and symptoms. Headache and visual disturbance are among the frequently seen as presenting symptom. Visual field (VF) assessment is one of the crucial component of neuroophtalmologic assessment and mean deviation (MD) value from automated perimetry allows quantification of the visual field defect. We formulated a study to look into the factors that affect the visual field outcome after surgery...

AbstractContext: Aggressive pituitary tumours causing Cushing's Disease are very rare, difficult to treat, and usually resistant to conventional therapy. There is growing evidence for the use of temozolomide (TZM), an alkylating chemotherapeutic agent, as first line chemotherapy in tumours resistant to repeated neurosurgery, radiotherapy and adrenalectomy. OBJECTIVE: To present the response to TMZ in a rare case of an aggressive pituitary tumour in the course of Cushing's Disease and to review the literature referring to similar cases...

We describe a novel patient position for endoscopic transphenoidal surgery - the 'conversational position'. This position is a safe and effective alternative to the standard supine position, incorporating a semi-sitting position with the additional innovation of achieving a 'conversational position' by flexing the neck and turning the patient's head turned to face the surgeon. The 'conversational' position offers improvements in the surgical approach to sellar region, addressing specific intraoperative challenges such as maintaining a bloodless operative field, and enabling more intuitive and ergonomic surgical workflow...

BACKGROUND: Most sellar gangliocytomas are discovered with a concurrent pituitary adenoma, also known as a mixed gangliocytoma-adenoma (MGA). MGAs are rare, with fewer than 100 cases reported in the literature to date and only 1 previously documented surgical series. Because MGAs are radiologically indistinguishable from pituitary adenomas, they are often diagnosed after surgery. Combined with the paucity of clinical outcome data for these tumors, this makes their diagnosis and management challenging...

The field of pituitary surgery was born in the first decade of the twentieth century in Europe, and it evolved rapidly with the development of numerous innovative surgical techniques by some of the founding fathers of neurosurgery. This study investigates the pioneering Italian treatise on pituitary surgery, La Patologia Chirurgica dell'Ipofisi (Surgical Pathology of the Hypophysis), published in 1911 by Giovanni Verga (1879-1923), a surgeon from Pavía and one of Golgi's disciples. This little-known monograph compiles the earliest experience on pituitary surgery through the analysis of the first 50 procedures performed between 1903 and 1911...

PURPOSE: Non-functioning pituitary adenomas are common, and the treatment and follow-up of these patients represent a multidisciplinary challenge. First line treatment is transphenoidal surgery, with debulking or total removal of tumour. A substantial portion of the tumours relapse after surgery, and there is no consensus of how to follow these patients postoperatively. Our aim was to characterize the postoperative growth of non-functioning pituitary adenomas and correlate it to clinical and paraclinical data...

SUMMARY: Corticotroph adenomas are extremely rare in children and adolescents. We present a 15-year-old boy who was investigated for delayed puberty (A1P2G1, bilateral testicular volumes of 3 mL each). There was no clinical or laboratory evidence suggestive of chronic illness, and the initial clinical impression was constitutional delay in puberty. Subsequently, MRI scan of the brain revealed the presence of a mixed cystic and solid pituitary lesion slightly displacing the optic chiasma...

Surgery is the primary treatment of choice for all symptomatic pituitary adenomas except prolactinomas. Common postoperative complications include endocrinopathies, vision impairment and cerebrospinal fluid leak. The present study assessed 153 continuous microscopic surgeries for pituitary adenomas performed by an author of the present study between 2010 to 2014. Patients underwent either transphenoidal or transcranial surgery depending on their individual tumor characteristics. Five typical cases are presented in the present study and intraoperative identification and preservation of the gland and stalk were discussed...
