OBJECTIVE: Most sellar gangliocytomas are discovered with a concurrent pituitary adenoma, also known as a mixed gangliocytoma-adenoma (MGA). MGAs are rare with less than 100 cases reported in the literature and only one previously documented surgical series. As MGAs are radiologically indistinguishable from pituitary adenomas, their diagnosis is often made following surgery. This, combined with the paucity of clinical outcome data for these tumors, makes their diagnosis and management challenging...

BACKGROUND: Walter E. Dandy (1886-1946) was an outstanding neurosurgeon who spent his entire career at the Johns Hopkins Hospital. After graduating from medical school in 1910, he completed a research fellowship in the Hunterian laboratory with Harvey Cushing and then joined the Department of Surgery as resident, rising to the rank professor in 1931. Dandy made several contributions that helped building the neurosurgical specialty, most famously the introduction of pneumo-ventriculography to image brain lesions for which he received a Nobel prize nomination...

Objective Intra-operative coagulopathy has a close relationship with blood loss and the prognosis of patients. Rapid-thrombelastography (r-TEG) is a comprehensive assessment of coagulation abnormalities and also an effective way for constructing blood transfusion. This study attempts to investigate the correlation of r-TEG indices with intra-operative hemorrhage.Methods Patients who underwent transphenoidal hypophysectomy and craniotomy from January 15 to April 30, 2013 in Peking Union Medical College hospital were recruited...

PURPOSE: In this study, we set out to define our institutional criteria for patient eligibility for transsphenoidal resection of parasellar meningiomas, and to report our experience with extended transnasal approaches for these lesions. We aimed to discuss the important considerations of patient selection and risk stratification to optimize outcomes for patients with these difficult lesions, and also include considerations that should be reviewed during surgical approach selection. METHODS: Medical records from Brigham and Women's Hospital were retrospectively reviewed for all patients who underwent transsphenoidal surgery for pituitary disease with the senior author from April 2008 to March 2017 (938 procedures)...

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...

OBJECTIVE: To assess outcomes after endoscopic endonasal surgery for recurrent or residual pituitary adenomas. METHODS: We retrospectively analyzed 61 patients from 2009 to 2016 who underwent endoscopic endonasal surgery for recurrent or residual pituitary adenomas after previous microscopic or endoscopic transsphenoidal operation. RESULTS: The previous surgical approach was endoscopic endonasal in 55.7% and microscopic in 44.2% of patients...

BACKGROUND: Turner syndrome (TS) is the most common sex chromosome abnormality in females, typically associated with primary amenorrhea and premature ovarian failure due to gonadal dysgenesis. The association of TS with hypopituitarism is an uncommon finding. The objective of the study was to describe an adolescent with TS with hypergonadotropic hypogonadism and subsequent hypogonadotropic hypogonadism. CASE PRESENTATION: A 16-year-old female with primary amenorrhea was diagnosed with TS based on karyotype 45,XO...

OBJECTIVES: Our objective was to analyze variations in the optic nerve (ON) course and surrounding structures in an effort to construct an optic nerve injury risk profile before endoscopic intranasal sphenoidal, or endoscopic endonasal transphenoidal, skull-base surgery, and eventually to construct and formulate a common classification by combining the known classes. The authors used computed tomography (CT) toward this end. METHODS: The authors retrospectively reviewed 200 consecutive CT scans (400 sides) of the paranasal sinuses...

OBJECTIVE Patient demographic characteristics, hospital volume, and admission status have been shown to impact surgical outcomes of sellar region tumors in adults; however, the data available following the resection of craniopharyngiomas in the pediatric population remain limited. The authors sought to identify potential risk factors associated with outcomes following surgical management of pediatric craniopharyngiomas. METHODS The Nationwide Inpatient Sample database and Kids' Inpatient Database were analyzed to include admissions for pediatric patients (≤ 18 years) who underwent a transcranial or transsphenoidal craniotomy for resection of a craniopharyngioma...

BACKGROUND: The pituitary adenoma causing acromegaly is typically resected through a transsphenoidal approach and visualized with an operating microscope or endoscope. We undertook a systematic review and meta-analysis examining the clinical efficacy of endoscopic and microsurgical approaches. METHODS: Relevant studies using either endoscopic or microscopic transsphenoidal approaches for growth hormone pituitary adenomas were identified until February 2016. Data were extracted and analyzed according to predefined clinical end points...

BACKGROUND: Idiopathic intracranial hypertension (IIH) in patients with Cushing disease (CD), after treatment, is rarely described, in adults. The cause is believed to be multifactorial, potentially related to a relative decrease in cortisol after surgical resection or medical treatment of a corticotroph pituitary adenoma. We investigate our center's CD database (140 surgically and 60 medically [primary or adjunct] treated patients) for cases of IIH, describe our center's experience with symptomatic IIH, and review treatment strategies in adults with CD after transsphenoidal resection...

Pituitary tuberculoma is extremely rare, even in endemic regions of tuberculosis and much less frequently as a presentation of pituitary apoplexy. We describe a 25-year-old female presented with sudden onset of headache and vision loss of left eye which mimicking symptoms of pituitary apoplexy. MRI of the pituitary gland showed a rim-enhancing lesion at the intrasellar region extending into the suprasellar area, but absence of posterior bright spot with enhancement of the pituitary stalk. Pituitary hormonal evaluation revealed panhypopituitarism and diabetes insipidus...
