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...

As one of the projects of the Adverse Events Study Group of the Foundation for Growth Science in Japan, the literatures on the recurrence and / or regrowth or new formation of brain tumors in patients treated with growth hormone (GH) were reviewed. Since the tumor volume of the sellar lesion can be accurately evaluated only by magnetic resonance imaging (MRI), the related literatures published after 1990 were retrieved by searching under keywords, such as GH, replacement therapy, brain tumor, recurrence, tumor formation, etc...

OBJECTIVE: Keyhole approaches are currently under investigation for skull base tumor surgery. They are expected to have a low complication rate with the same successful resection rate compared to endoscopic endonasal procedures. In this study, the authors compare their current series of tuberculum sellae meningiomas resected via an endoscopic endonasal or microsurgical supraorbital keyhole approach. METHODS: Between 2011 and 2016, 16 patients were treated using the supraorbital keyhole procedure and 6 patients received an endoscopic endonasal procedure...

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...

BACKGROUND: Papillary craniopharyngioma (PCP) are uncommon variants of craniopharyngiomas (CP), which are benign epithelial neoplasms of the sellar and suprasellar region. Histologically, PCPs are typically composed of well-differentiated stratified squamous epithelium; however, focal variations are not uncommon. A distinction from other lesions of the region, despite being difficult to achieve due to the overlapping radiological and clinical features, is important for adequate treatment to be administered...

OBJECTIVE: Various pathologies can occur in the sellar and suprasellar regions. The potential of fluorine-18 fluorodeoxyglucose (FDG) positron emission tomography (PET) for the preoperative evaluation of sellar and parasellar lesions was investigated. METHODS: A total of 49 patients aged 8 to 82 years with sellar and parasellar macroscopic lesions (≥10 mm) underwent FDG PET. Twenty-two patients had pituitary adenomas, including 14 non-functioning and 8 growth hormone (GH)-secreting adenomas...

John Richard Apps, Juan Pedro Martinez-Barbera
Adamantinomatous craniopharyngioma (ACP) is the commonest tumor of the sellar region in childhood. Two genetically engineered mouse models have been developed and are giving valuable insights into ACP biology. These models have identified novel pathways activated in tumors, revealed an important function of paracrine signalling and extended conventional theories about the role of organ-specific stem cells in tumorigenesis. In this review, we summarize these mouse models, what has been learnt, their limitations and open questions for future research...

Craniopharyngiomas (CPs) are usually benign, non-metastasizing embryonic malformations originating from the sellar area. They are, however, locally invasive and generate adherent interfaces with the surrounding brain parenchyma. Previous studies have shown the tumor microenvironment is characterized by a local abundance of Adenosine Triphosphate (ATP), infiltration of leukocytes, and elevated levels of pro-inflammatory cytokines that are thought to be responsible, at least in part, for the local invasion. Here we examine whether ATP, via the P2X7R, participates in the regulation of cytokine expression in CPs...

The skull base is a complex anatomical region that harbors many important neurovascular structures in a relatively confined space. The pathology that can develop at this site is varied, and many disease processes may present with similar clinical and neuroimaging findings. While computed tomography maintains a role in the evaluation of many entities and can, for instance, delineate osseous erosion with great detail and characterize calcified tumor matrices, magnetic resonance imaging (MRI) is the mainstay in the neuroimaging assessment of most pathology occurring at the skull base...

Context: De novo brain tumors developing after treatment of pituitary/sellar lesions have been reported, but it is unknown whether this is linked to any of the treatment modalities. Objective: To study the occurrence of malignant brain tumors and meningiomas in a large cohort of patients treated for pituitary/sellar lesions, with special emphasis on the role of radiotherapy (RT). Patients and Methods: Patients (n = 8917) who were hypopituitary due to pituitary adenomas, craniopharyngiomas, and other sellar tumors followed in KIMS (Pfizer International Metabolic Database) from 1994 to 2012 were included...

Atypical teratoid/rhabdoid tumors (AT/RTs) are rare aggressive tumors of the central nervous system that predominantly affect infants. Although adult AT/RT are rare, accumulated cases have revealed adult-specific AT/RT in the sellar region. Twelve previously reported cases of sellar AT/RT exclusively occurred in adult females, suggesting biological differences from conventional infant AT/RT. We herein investigated a series of 6 sellar AT/RT for histopathologic features, the molecular status of the INI1/SMARCB1 gene, and clinical courses...

OBJECTIVES: No clear consensus yet defines the endpoints for operative learning curves in the transition to minimally invasive endoscopic techniques. This retrospective review of our first 202 patients who underwent endoscopic pituitary resection examines the statistical learning curve related to operative times--a measure of our surgical team's efficiency and complication rates, a reflection of surgical skill and maturity. METHODS: Retrospective chart review included patient demographics, tumor type, operative times, complication rates, and follow-up...

The sellar xanthogranuloma is a rare lesion of the sellar-parasellar region difficult to differentiate from other tumors such as craniopharyngiomas or Rathke's cleft cyst in the preoperative evaluation. As they are recently recognized as a separate entity and the few number of reports in the literature, its etiology is unknown and its impact remains uncertain. This article will describe the first three cases reported in Latin America, identified in one of them an imaging feature that may be helpful to elucidate an imaging growth pattern...

OBJECTIVE: Neurosurgical techniques for the treatment of sellar pathologies have been evolving continuously over the last decades. Additionally to the innovation of approaches and surgical techniques, this progress yielded to the application of modern intraoperative surgical tools as well as peri- and intraoperative imaging. Until now, no long-term analysis of the impact of new therapy concepts on the patient's outcome exists. Aim of this study was to analyse the impact of new operative approaches on perioperative mortality and morbidity as well as the long-term outcome after pituitary surgery...

We report here a rare case of symptomatic granular cell tumor (GCT) of the sellar region with a large calcification. A 70-year-old woman presented with a sellar mass, accompanied by bitemporal hemianopia. The patient was diagnosed preoperatively as having a craniopharyngioma or a pituitary adenoma, because of the large calcification. The patient underwent surgical tumor resection via endoscopic trans-sphenoidal surgery and was diagnosed pathologically as having GCT. The patient's postoperative course was uneventful and her visual field disturbance improved soon after the operation...
