Abstract
BACKGROUND Craniopharyngioma is a common intracranial tumour in children. Clinical manifestations are related to hypothalamic/pituitary deficiencies, visual impairment, and increased intracranial pressure. Defects in pituitary function cause shortages of growth hormone, gonadotropin, corticotropin, thyrotropin, and vasopressin, resulting in short stature, delayed puberty, feebleness, lethargy, polyuria, etc. However, manifestations involving precocious puberty (PP) are rare. CASE REPORT In both patients, surgical resection was performed after the diagnosis of craniopharyngioma, and breast development occurred postoperatively at one month in one patient and at one year and three months in the other patient. Central precocious puberty (CPP) was diagnosed via relevant examinations. Leuprorelin was injected subcutaneously every 28 days, and changes in height, weight, bone age, gonadal ultrasound and sex hormones were recorded. During the follow-up of the two children, the sex hormone levels were significantly reduced, and significant acceleration in bone age was not observed. CONCLUSIONS CPP was induced by craniopharyngioma surgery, and treatment with gonadotropin-releasing hormone analogues (GnRHa) inhibited sexual development and bone age progression. More attention should be given to monitoring for CPP during long-term follow-up of craniopharyngiomas in the clinic.

Abstract
Since hypothalamic obesity (HyOb) was first described over 120 years ago by Joseph Babinski and Alfred Fröhlich, advances in molecular genetic laboratory techniques have allowed us to elucidate various components of the intricate neurocircuitry governing appetite and weight regulation connecting the hypothalamus, pituitary gland, brainstem, adipose tissue, pancreas, and gastrointestinal tract. On a background of an increasing prevalence of population-level common obesity, the number of survivors of congenital (eg, septo-optic dysplasia, Prader-Willi syndrome) and acquired (eg, central nervous system tumors) hypothalamic disorders is increasing, thanks to earlier diagnosis and management as well as better oncological therapies. Although to date the discovery of several appetite-regulating peptides has led to the development of a range of targeted molecular therapies for monogenic obesity syndromes, outside of these disorders these discoveries have not translated into the development of efficacious treatments for other forms of HyOb. This review aims to summarize our current understanding of the neuroendocrine physiology of appetite and weight regulation, and explore our current understanding of the pathophysiology of HyOb.

Abstract
Tumours of the anterior part of the pituitary gland represent just 1% of all childhood (aged <15 years) intracranial neoplasms, yet they can confer high morbidity and little evidence and guidance is in place for their management. Between 2014 and 2022, a multidisciplinary expert group systematically developed the first comprehensive clinical practice consensus guideline for children and young people under the age 19 years (hereafter referred to as CYP) presenting with a suspected pituitary adenoma to inform specialist care and improve health outcomes. Through robust literature searches and a Delphi consensus exercise with an international Delphi consensus panel of experts, the available scientific evidence and expert opinions were consolidated into 74 recommendations. Part 1 of this consensus guideline includes 17 pragmatic management recommendations related to clinical care, neuroimaging, visual assessment, histopathology, genetics, pituitary surgery and radiotherapy. While in many aspects the care for CYP is similar to that of adults, key differences exist, particularly in aetiology and presentation. CYP with suspected pituitary adenomas require careful clinical examination, appropriate hormonal work-up, dedicated pituitary imaging and visual assessment. Consideration should be given to the potential for syndromic disease and genetic assessment. Multidisciplinary discussion at both the local and national levels can be key for management. Surgery should be performed in specialist centres. The collection of outcome data on novel modalities of medical treatment, surgical intervention and radiotherapy is essential for optimal future treatment.

Pediatric craniopharyngioma: a 20-year study on epidemiological features, clinical presentation, and survival outcomes in a tertiary care center from LMIC. Childs Nerv Syst 2024; 40:427-434. [PMID: 37837454 DOI: 10.1007/s00381-023-06177-8] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/13/2023] [Accepted: 09/30/2023] [Indexed: 10/16/2023]
Abstract
INTRODUCTION Craniopharyngioma constitutes approximately 10% of primary brain tumors in children. It can cause considerable morbidity and mortality due to the local aggressiveness of the tumor itself or its management affecting the hypothalamus-pituitary axis and optic pathway involvement. There is very scarce data available from LMIC which makes the management controversial where multidisciplinary teams are already not available in most of the centers. This is a single-center cross-sectional retrospective review of 20-year record of 49 patients with craniopharyngioma treated between 2001 and 2020 at Aga Khan University Hospital, a tertiary care center in Karachi, Pakistan. METHODS We have assessed the epidemiological data of children presenting with the diagnosis of craniopharyngioma, treatment modalities used, and neurological, endocrine, and hypothalamic complications in these patients. The assessment involved a retrospective review of medical records and medical follow-up. RESULTS Out of a total of 49 patients, 26 (53%) were male, and 23 (46.9%) were female. The mean age was 9.5 years (SD ± 4.5 years). Most common symptoms at initial presentation were headache 41 (83.6%), visual deficit 40 (81.6%), nausea and vomiting 26 (53%), and endocrine abnormalities 16 (32%). Treatment modalities used at our center include gross total resection 11 (22%) and subtotal resection 38 (77%) out of total, while 6 (12.2%) patients received intracystic interferon. Histopathologic findings of the majority of patients (40 (81%)) revealed an adamantinomatous type of tumor. Only 23 (46.9%) children followed in clinic post-op. Median follow-up after craniopharyngioma presentation was 5 years (± 2.1 SD, range: 2-10 years). Pituitary hormone deficiencies (98%) and visual disturbances (75%) were the most common long-term health conditions observed. CONCLUSIONS Since pituitary hormone deficiencies and visual disturbance were the most common long-term health conditions observed in our study, these patients require a multidisciplinary team follow-up to improve their quality of life.

Abstract
PURPOSE OF REVIEW Craniopharyngiomas represent one of the most challenging diseases to treat. Despite their benign histology, and after many decades of surgical experience and technological advancements, there is still no clear consensus regarding the most effective management for this tumor. Due to their location and aggressive local characteristics, purely surgical approaches all too often result in unacceptable morbidity. RECENT FINDINGS Partial resection combined with radiation therapy results in similar control rates when compared to aggressive surgery, while also minimalizing the neuro-endocrinological morbidity. In this manuscript, we describe the historical progression of the shifting strategies in the management of pediatric craniopharyngioma. Time has also altered our expectations for outcomes, evolving from purely morbidity and mortality to simple Glasgow Outcomes Scales, now to formal neuro-psychometric and quality of life data.

Abstract
Quality of life (QoL) is a critical component of aftercare in survivors of childhood-onset craniopharyngioma (CP). Visual impairment adversely affects QoL after CP. This study assessed the frequency of visual impairment in patients with CP and its association with QoL. This study analyzed vision-related QoL in patients recruited 2000-2019 in the prospective cohort studies KRANIOPHARYNGEOM 2000/2007. Ophthalmologic examinations were performed at diagnosis, three, 12, and 36 months, respectively after the diagnosis. The QoL (PEDQOL) scores, were also evaluated at three, 12, and 36 months, respectively after the CP diagnosis. Multivariable logistic regression was used to analyze factors associated with visual impairment during follow-up. One-hundred twenty patients were included in this study. On ophthalmological examination, visual impairment was observed in the majority of the patients (n = 84, 70%) at CP diagnosis. After surgery, vision was restored in 27 patients (32%) with visual impairment at diagnosis. In the first (p = 0.017) and third (p = 0.011) year after diagnosis, parents of patients with visual impairment reported lower social functioning (family). Reduced autonomy was found three years after diagnosis in self- (p = 0.029) and parental (p = 0.048) assessments. Next to visual impairment at diagnosis, no additional risk factors for visual impairment during follow-up could be identified. Visual impairment has a clinically relevant impact on QoL after CP. The visual status at CP diagnosis determines the visual outcome during follow-up. Early detection of visual impairment, regular QoL assessments, and risk-appropriate aftercare are recommended.Clinical Trial Registration KRANIOPHARYNGEOM 2000 (Clinical trial registration number: NCT00258453) and KRANIOPHARYNGEOM 2007 (Clinical trial registration number: NCT01272622).

Abstract
Although rare, craniopharyngiomas constitute up to 80% of tumours in the hypothalamic-pituitary region in childhood. Despite being benign, the close proximity of these tumours to the visual pathways, hypothalamus, and pituitary gland means that both treatment of the tumour and the tumour itself can cause pronounced long-term neuroendocrine morbidity against a background of high overall survival. To date, the optimal management strategy for these tumours remains undefined, with practice varying between centres. In light of these discrepancies, as part of a national endeavour to create evidence-based and consensus-based guidance for the management of rare paediatric endocrine tumours in the UK, we aimed to develop guidelines, which are presented in this Review. These guidelines were developed under the auspices of the UK Children's Cancer and Leukaemia Group and the British Society for Paediatric Endocrinology and Diabetes, with the oversight and endorsement of the Royal College of Paediatrics and Child Health using Appraisal of Guidelines for Research & Evaluation II methodology to standardise care for children and young people with craniopharyngiomas.

Abstract
PURPOSE Craniopharyngiomas (CPGs) are aggressive brain tumors responsible of severe morbidity in children. The best treatment strategies are under debate. Our study evaluates surgical, pituitary, and hypothalamic outcomes of a tailored staged-surgical approach compared to a single-stage radical approach in children with CPGs. METHODS Multicenter retrospective study enrolling 96 children treated for CPGs in the period 2010-2022. The surgical management was selected after a multidisciplinary evaluation. Primary endpoint includes the inter-group comparison of preservation/improvement of hypothalamic-pituitary function, the extent of resection, and progression-free survival (PFS). Secondary endpoints include overall survival (OS), morbidity, and quality of life (QoL). RESULTS Gross Total Resection (GTR) was reached in 46.1% of cases in the single-stage surgery group (82 patients, age at surgery 9 ± 4.7 years) and 33.3% after the last operation in the staged surgery group (14 patients age 7.64 ± 4.57 years at first surgery and 9.36 ± 4.7 years at the last surgery). The PFS was significantly higher in patients addressed to staged- compared to single-stage surgery (93.75% vs 70.7% at 5 years, respectively, p = 0.03). The recurrence rate was slightly higher in the single-stage surgery group. No significant differences emerged in the endocrinological, visual, hypothalamic outcome, OS, and QoL comparing the two groups. CONCLUSIONS In pediatric CPGs' surgical radicality and timing of intervention should be tailored considering both anatomical extension and hypothalamic-pituitary function. In selected patients, a staged approach offers a safer and more effective disease control, preserving psychophysical development.

Abstract
PURPOSE To assess the predictive value for functional recovery of Ganglion Cell Complex Layer (GCC) and Retinal Nerve Fiber Layer (RNFL) measurements obtained by Optical Coherence Tomography (OCT) in patients undergoing chiasmal decompression and to define potential OCT thresholds for visual recovery. METHODS We measured preoperative GCC and RNFL thickness in patients with a sellar and/or perisellar tumor compressing the optic chiasm. Visual recovery was defined as recovery of mean deviation (MD) and pattern standard deviation (PSD) using Humphrey visual field testing after 12 successful decompressions (24 eyes). Receiver operating characteristic curve (ROC) analysis was used to identify the best thresholds. RESULTS Robust global and focal OCT thresholds were found. Superior GCC≥63μm had the best functional prognostic value (AUC=1) for visual improvement. Mean GCC ≥ 67μm and mean RNFL≥75μm also had excellent predictive values (AUC>0.9). CONCLUSION In this preliminary study, significant preoperative OCT thresholds for early visual recovery after chiasmal decompression were identified, mainly regarding GCC measurements. Further studies on larger cohorts with closely scheduled follow-up could refine our results.

World Neurosurg 2021; 148:e589-e599. [PMID: 33482413 DOI: 10.1016/j.wneu.2021.01.044] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2020] [Revised: 01/10/2021] [Accepted: 01/10/2021] [Indexed: 11/20/2022]
Abstract
BACKGROUND Because of involvement of the optic apparatus, craniopharyngiomas frequently present with visual deterioration. Although visual improvement is a primary goal of surgical intervention, prediction models are lacking. METHODS We retrospectively reviewed all patients undergoing craniopharyngioma surgery at a single institution (2014-2019). Preoperative, intraoperative, and postoperative variables of interest were collected. Visual acuity and visual fields (VFs) were standardized into Visual Impairment Scores (VISs), defined by the German Ophthalmological Society. VIS ranged from 0 (normal vision) to 100 (complete bilateral blindness). Visual improvement/deterioration was defined as a postsurgical decrease/increase of ≥5 VIS points, respectively. RESULTS Complete ophthalmologic assessments were available for 61 operations, corresponding to 41 patients (age, 4-73 years). Vision improved after 28 operations (46%), remained stable after 27 (44%), and deteriorated after 6 (10%). In bivariate analysis, significant predictors of visual improvement included worse preoperative VIS (odds ratio [OR], 1.058; P < 0.001), worse preoperative VF mean deviation (OR, 1.107; P = 0.032), preoperative vision deficits presenting for longer than 1 month (OR, 6.050; P = 0.010), radiographic involvement of the anterior cerebral arteries (OR, 3.555; P = 0.019), and gross total resection (OR, 4.529; P = 0.022). The translaminar surgical approach was associated with visual deterioration (OR, 6.857; P = 0.035). In multivariate analysis, worse preoperative VIS remained significantly associated with postoperative visual improvement (OR, 1.060; P = 0.011). Simple linear correlation (R2=0.398; P < 0.001) suggests prediction of postoperative VIS improvement via preoperative VIS. CONCLUSIONS Patients with reduced preoperative vision, specific radiographic vascular involvement, and gross total resection showed increased odds of visual improvement, whereas the translaminar approach was associated with visual deterioration. Such characteristics may facilitate patient-surgeon counseling and surgical decision making.

Abstract
BACKGROUND Craniopharyngioma has historically been recognized to be a formidable pathology primarily due to its proximity to critical neurovascular structures and the challenging surgical corridors that surgeons have tried to reach this lesion. FOCUS OF REVIEW In this work, we review the medical and surgical management of these tumors with a focus on clinical presentation, diagnostic identification, surgical approach, and associated adjuvant therapies. We will also discuss our current treatment paradigm using endoscopic, open, and combined approaches to craniopharyngiomas. The management of craniopharyngiomas requires a multidisciplinary team of surgeons, endocrinologists, and neuroanesthesiologists as well as neurocritical care specialists to deliver the most comprehensive and safest surgical resection with minimal postoperative morbidity.

Abstract
PURPOSE Craniopharyngioma often causes visual loss due to the close relation to the anterior visual pathways. This study investigates the incidence and predictors of visual outcomes in patients with craniopharyngioma. METHODS Data from sixty-six patients who underwent surgery for craniopharyngioma from 2009 to 2013 in Denmark were reviewed. Primary outcomes were visual acuity (VA) and visual field (VF) defects from pre-and postoperative visits. Secondary outcomes were optic nerve atrophy (OA) and papilledema. RESULTS Fifty-eight patients were included. The VA of the patients 1-year after surgery improved by -0.16 log(MAR) (95%CI: -0.30 to -0.02; p = 0.0266). Visual field (VF) defects worsened in 17 eyes (30%), remained stable in 21 eyes (37%) and improved in 19 eyes (33%). The presence of papilledema and the absence of OA were significantly correlated with an improvement in VA postoperatively (p = 0.011 and p = 0.011, respectively). Patients undergoing surgery within a week or less after their first ophthalmological examination had a significant improvement in VA (-0.36; 95%CI: -0.62 to -0.09; p = 0.0099). Patients undergoing surgery using a subfrontal approach also showed improvement in VA (p = 0.048). Tumour recurrence had a significantly worse VA outcome (p = 0.0074). CONCLUSION Patients show a slight improvement in VA 1-year after operation for craniopharyngioma. The presence of papilledema and early surgical intervention is associated with a significant improvement in VA. Early involvement of a dedicated ophthalmologist is recommended to secure an early detection of a visual decline and potential tumour recurrence.

Abstract
Visual function is a critical factor in the diagnosis, monitoring, and prognosis of craniopharyngiomas in children. The aim of this study was to report the long-term visual outcomes in a cohort of pediatric patients with craniopharyngioma. The study design is a retrospective chart review of craniopharyngioma patients from a single tertiary-care pediatric hospital. 59 patients were included in the study. Mean age at presentation was 9.4 years old (range 0.7-18.0 years old). The most common presenting features were headache (76%), nausea/vomiting (32%), and vision loss (31%). Median follow-up was 5.2 years (range 1.0-17.2 years). During follow-up, visual decline occurred in 17 patients (29%). On Kaplan Meier survival analysis, 47% of the cases of visual decline occurred within 4 months of diagnosis, with the remaining cases occurring sporadically during follow-up (up to 8 years after diagnosis). In terms of risk factors, younger age at diagnosis, optic nerve edema at presentation, and tumor recurrence were found to have statistically significant associations with visual decline. At final follow-up, 58% of the patients had visual impairment in at least one eye but only 10% were legally blind in both eyes (visual acuity 20/200 or worse or < 20° of visual field). Vision loss is a common presenting symptom of craniopharyngiomas in children. After diagnosis, monitoring vision is important as about 30% of patients will experience significant visual decline. Long-term vision loss occurs in the majority of patients, but severe binocular visual impairment is uncommon.

Abstract
OBJECTIVE To investigate the use of peripapillary optical coherence tomography for monitoring optic neuropathy in pediatric craniopharyngioma. DESIGN Retrospective, consecutive-cohort, single-centre chart analysis. PARTICIPANTS Twenty children with craniopharyngioma treated at a pediatric medical centre from 1999 to 2011. METHODS The medical files were reviewed for demographics and optic nerve function. Findings for visual acuity and visual fields were analyzed against repeated optical coherence tomography (OCT) measurements of peripapillary nerve fibre layer thickness (using either time-domain Stratus OCT or spectral-domain Cirrus OCT). RESULTS Average age at diagnosis was 6.5 ± 3.88 years. The most common presenting symptom was headache; only 1 child complained of visual loss. Mean best corrected visual acuity (logMAR) was 0.036 ± 0.06 in the 17 healthy eyes and 1.05 ± 1.45 in the 23 eyes with optic neuropathy. Positive signs included relative afferent pupillary defect (8/20), visual acuity loss (7/20), temporal visual field loss (bilateral 4/15, unilateral 4/15), papilledema (3/20), and unilateral/bilateral optic disc pallor (14/20). RNFL thickness was significantly lower in eyes with optic neuropathy than in healthy eyes (65 ± 22 µm vs 86.2 ± 29 µm; p = 0.000) and correlated with visual acuity (r = -0.43 to -0.17, p = 0.0001) and presence or absence of a visual field defect (mean difference, 26.1 ± 5.8 µm, p = 0.003). Ten children showed no change in RNFL thickness over time (mean 18 ± 14.2 months). CONCLUSIONS A thinner RNFL on ocular coherence tomography is correlated with poorer visual acuity and visual field loss. Ocular coherence tomography may serve as an objective method to quantify axonal loss caused by craniopharyngioma. Further investigation is needed to determine its use for evaluating progressive axonal loss over time.

Abstract
Abstract
BACKGROUND:
Craniopharyngiomas (CRPs) often cause visual deterioration (VD) due to the close vicinity of the optic apparatus.
OBJECTIVE:
To evaluate longitudinal visual outcomes after surgery of CRP and determine the prognostic factors thereof.
METHODS:
One hundred forty-six adult patients who underwent surgery for newly diagnosed CRP were retrospectively reviewed. There were 87 male patients (60%), and the median age was 41 years (range, 18–75). The mean follow-up duration was 88.7 months (range, 24–307). A visual impairment score was used to assess the short-term (<1 month) and long-term (>2 years) visual outcomes.
RESULTS:
Gross total removal was performed in 53 patients (36%), and tumor recurrence occurred in 40 patients (27%). The average preoperative, short- and long-term visual impairment scores were 44.4, 38.5, and 38.1, respectively, on a 0- to 100-point scale (with 100 indicating the worst vision). Short- and long-term VD occurred in 28 (19%) and 39 patients (27%), respectively. Subtotal removal (STR) alone (P = .010; OR = 4.8), short-term VD (P < .001; OR = 39.7), and tumor recurrence (P < .001; OR = 28.2) were significant risk factors for long-term VD in the multivariate analysis. Patients undergoing STR alone had higher tumor recurrence rates in comparison with those who underwent gross total removal or STR with adjuvant therapy (P < .001).
CONCLUSION:
Short-term VD secondary to the surgical insult and the recurrence of the tumor were strong predictors of long-term visual outcomes after surgical treatment for CRP. STR alone may be an ineffective strategy for achieving tumor control and optimal visual outcomes in patients with CRP.

Abstract
PURPOSE The aim of this study was to investigate the significance of the initial visual field as a predictor of recurrence of craniopharyngioma and postoperative visual outcome in children with craniopharyngioma. METHODS A retrospective analysis was performed on 27 children 15 years of age or younger with craniopharyngioma. Records of clinical features including ocular and systemic symptoms, optic disc findings, and size of the tumor were analyzed according to preoperative visual field. Postoperative visual acuities, visual fields, and recurrence rates were also evaluated. RESULTS Preoperatively, 13 patients had a normal visual field and 14 patients had various visual field defects. The size of the tumor was not correlated with the preoperative visual field defects (P = .15). Preoperative visual field defects were associated with polyuria and polydipsia (P = .01), higher recurrence (P < .001), and poorer postoperative visual acuities (P < .001). CONCLUSION Preoperative visual field can be a reliable clinical indicator of systemic manifestations, recurrence, and postoperative visual outcome in children with craniopharyngioma.

Abstract
An audit of treatment regimens at presentation, recurrence and survival rates spanning 37 years were reviewed for children and adults with craniopharyngioma treated at The Prince of Wales or the Sydney Children's hospitals. Eligibility criteria stipulated all patients (n=41) received radiotherapy as part of their treatment course. The primary end point for evaluation was the incidence of radiological progression post-radiotherapy, and secondary end-points were the symptomatic and hormonal status post-radiotherapy. There were 12 paediatric patients (age, <16 years) and 29 adults (age range, 16-80 years). Of the 41 patients, 39 had a suprasellar tumour component, and 38 had radiologically persistent disease post-surgery. Four patients were treated by radiosurgery (median volume treated, 3.5 cm(3)); four patients progressed post-radiotherapy, of whom two were salvaged by further radiotherapy, one succumbed to progressive local disease, and one had a small intrasellar recurrence surgically resected. Progression-free survival (95.12%) was followed for up to 23 years. Thus, subtotal resection and the modern radiotherapy approach is likely to provide excellent patient and disease outcomes.

Abstract
Since children may not be able to complain of progressive reduction in optic acuity, visual assessment in infancy may present practical difficulties. The authors report a case of craniopharyngioma, which led a young child to early blindness before the correct diagnosis could be made. Similar to other reported cases, the authors found that surgery did not substantially modify the preoperative visual deficit. They conclude that minimal improvement in visual acuity can be expected despite successful microsurgical removal of the tumor.

Abstract
Craniopharyngiomas are epithelial tumors arising along the path of the craniopharyngeal duct and presenting with a variety of manifestations. Their optimal management remains a subject of debate. Currently, surgical excision followed by external beam irradiation is the main treatment option. Craniopharyngiomas are associated with significant long-term morbidity and mortality rates.

Abstract
Craniopharyngiomas are rare benign epithelial tumors, arising from the pituitary stalk or gland and developing in the sellar and suprasellar region, affecting both adults and children. Incidence is 0.5 to 2 new cases per million inhabitants. Clinical features essentially include visual disturbances, endocrine deficiencies, and neurological signs. Initial signs are often visual loss and increased intracranial pressure in children, growth and pubertal delay in teenagers, visual disturbances or cognitive impairment in adults. Diagnosis is made on MRI and CT scan, demonstrating a sellar or suprasellar tumor, heterogeneous, with frequent calcifications. Craniopharyngiomas can be classified depending on their locations from the sella, the diaphragma sellae, and upon their origins from the pituitary stalk or the infundibulum. They can also be classified depending on the location from the optic chiasm and the third ventricle. This classification allows surgical series comparison, which is of importance since developments and extensions of the tumor can explain surgical difficulties. The management of this lesion is still controversial. Because it is an extra-cerebral benign lesion, the ideal goal of treatment should be complete tumor removal with improvement of altered visual functions, minimal deterioration of endocrine function, and no neuropsychological impairment. But the situation of the tumor, its relationship with third ventricle, hypothalamus, optic tract, vascular structures make its removal often difficult. However, great progresses have been realized in surgical treatment, resulting in a dramatic improvement of the prognosis of craniopharyngiomas. Nowadays, one can expect total removal in 60 to 70% of patients, subtotal removal in 20 to 30%, and partial removal in 10%. When total removal is impossible, radiotherapy may reduce the risk of a poor evolution. Recurrences are a problem in 15% of patients with total removal, 35% in subtotal removal, 70% in partial removal. If radiotherapy has not been performed as first treatment, it is efficient in 80% of recurrences. Long term follow up is necessary in these patients, due to medical management of endocrine, visual and psychological problems, and risk of late recurrence. With close involvement in this management, most of patients may enjoy a good outcome, 80% being able to return to normal active life.

Abstract
Craniopharyngiomas are rare, mainly sellar/parasellar, epithelial tumors diagnosed during childhood or adult life. Histologically, two primary subtypes have been recognized (adamantinomatous and papillary) with an as yet, unclarified pathogenesis. They may present with a variety of manifestations (neurological, visual, and hypothalamo-pituitary). Despite their benign histological appearance, they often show an unpredictable growth pattern, which, combined with the lack of randomized studies, poses significant difficulties in the establishment of an optimal therapeutic protocol. This should focus on the prevention of recurrence(s), improvement of survival, reduction of the significant disease and treatment-related morbidity (endocrine, visual, hypothalamic, neurobehavioral, and cognitive), and preservation of the quality of life. Currently, surgical excision followed by external beam irradiation, in cases of residual tumor, is the main treatment option. Intracystic irradiation or bleomycin, stereotactic radiosurgery, or radiotherapy and systemic chemotherapy are alternative approaches; their place in the management plan remains to be assessed in adequately powered long-term trials. Apart from the type of treatment, the identification of clinical and imaging parameters that will predict patients with a better prognosis is difficult. The central registration of patients with these challenging tumors may provide correlates between treatments and outcomes and establish prognostic factors at the pathological or molecular level that may further guide us in the future.

Abstract
In summary, much progress has been made in our understanding of childhood craniopharyngiomas. These histologically benign but "geographically malignant" tumors are challenging to treat and require experienced clinicians from multiple disciplines including neurosurgery, radiology, hematology/oncology, ophthalmology, endocrinology, and general pediatrics to address the multiple issues that arise with diagnosis, treatment, and long-term follow-up of affected children. The study and close observation of patients who have craniopharyngiomas may also be beneficial for our general understanding of pathophysiologic processes such as the observed "growth without growth hormone" phenomenon or the well-described and studied hypothalamic obesity phenotypes.

Abstract
BACKGROUND Medium- and long-term prognosis of craniopharyngioma is overwhelmed by the risks of hypothalamic and visual impairment. This problem has been underestimated for a long time because the major concern for the neurosurgeon was the risk of recurrences, their best prevention being thought to be complete tumour resection. Today, we know that radical surgery not only is not an absolute guarantee against recurrences but also can cause hypothalamic and visual complications. METHODS The authors suggest that instead of complete removal, the first choice treatment should be, when possible, a less aggressive, multistaged and personalized treatment. In this perspective they focus on other therapeutic methods: endocavity treatment of cysts with rhenium-186, triconformational radiotherapy, radiosurgery, and widespread use of the trans-sphenoidal approach. CONCLUSIONS These simple methods should reduce the risks of visual aggravation and metabolic syndrome.

Abstract
BACKGROUND Craniopharyngiomas account for 2-5% of all primary intracranial tumours. Despite their benign histological appearance, they are often associated with an unfavourable prognosis and their optimal treatment remains controversial. AIM To analyse the natural history and treatment outcome of children and adults presenting to the Departments of Paediatrics and Endocrinology with craniopharyngioma between 1964 and 2003. PATIENTS AND METHODS The records of 121 patients (age range 2.5-83 years, 42 aged < 16 and 79 aged > or = 16) were identified. The mean follow-up period since presentation was 103 months (8.6 years) (range 0.3-468 months). Sixteen patients underwent gross total removal (A), 3 gross total removal + radiotherapy (B), 51 partial removal (C), 33 partial removal + radiotherapy (D), 6 cyst evacuation alone (E) and 3 cyst evacuation + radiotherapy (F). The clinical, imaging and endocrinological data at presentation and during follow-up were analysed. RESULTS Headache and visual field defects were the most common presenting clinical features (64% and 55%, respectively). Ninety-four per cent of the tumours had an extrasellar component and 23% of them were associated with hydrocephalus. There was a significant difference in the recurrence-free survival rates between groups A-D [at 10 years: 100% (A), 100% (B), 38% (C) and 77% (D), P < 0.01], which persisted even when analysing patients operated after 1980. The median time of first recurrence was 2.5 years (range 0.5-36). The peri-operative mortality of the patients who had any type of neurosurgical intervention due to recurrence was higher than that observed after primary surgery (24%vs. 1.8%) (P < 0.01). The rate of re-accumulation of the cyst fluid was 58% during the first year in patients of group E, whereas none of the subjects of group F experienced such an event during their follow-up period. There was no reversal of pre-existing pituitary hormone deficits after any surgical intervention. The probabilities of GH, FSH/LH, ACTH, TSH deficiency and diabetes insipidus at the 10-year follow-up were 88%, 90%, 86%, 80% and 65%, respectively. After excluding the non-tumour-related deaths, the 10-year survival rate following presentation was 90%. Patients with recurrence had a significantly lower probability for survival compared with those without it (at 10 years: 70%vs. 99%, P < 0.01). At the 10-year follow-up the probability of the presence of major visual field defects was 48%, hyperphagia/obesity 39%, epilepsy 12% and hemi-/monoparesis 11%. In this large series no substantial differences in the outcome of tumours diagnosed during childhood or adult life were found. CONCLUSIONS Craniopharyngiomas remain tumours associated with significant morbidity. Gross total removal provides favourable results in terms of recurrences. If this cannot be achieved safely, adjuvant radiotherapy is beneficial in preventing tumour re-growth. Childhood- and adult-onset lesions generally behave similarly.

Abstract
PURPOSE To assess the clinical presentation and long-term visual outcome in a series of patients with craniopharyn-gioma. METHODS Retrospective case review. RESULTS Thirty-six patients were reviewed, comprising 19 female patients and 17 male patients. The age range was 2-77 years with a bimodal distribution of 17 children (mean age 10 years) and 19 adults (mean age 47 years). Blurred vision was the most common visual complaint (23 cases, 64%) and headache the most frequent systemic complaint (19 cases, 53%). The average duration of systemic symptoms was 45 weeks compared to 10 weeks for visual symptoms. Deficits in visual acuity occurred in 13 patients (36%) and showed no significant change from initial presentation to final review. Sixteen patients (44%) had bitemporal hemianopia on presentation and pleomorphism (change from one type of visual field defect to another) occurred in 11 patients. Recurrence of tumour occurred in 15 patients (42%) and was more likely in children (59%) than adults (26%). The mean time period to recurrence was 7 years. The average follow-up period for all cases was 10 years. CONCLUSION Patients with craniopharyngioma generally present late, and the visual symptoms are often preceded by a long history of systemic symptoms. Children are more likely to present with systemic symptoms than adults. Visual field pleomorphism is a feature of craniopharyngioma and occurred in one-third of the patients. Local recurrence is common. Although magnetic resonance imaging is the recommended means of follow up, regular neuro-ophthalmic review is useful in the early detection of anterior visual pathway compression by recurrent tumour.

Abstract
OBJECT This work is devoted to a 25-year retrospective study of 122 cases of craniopharyngiomas in adults and children treated and followed by the same neurosurgeon (R.V.E.). In this homogeneous series, the aim was total microsurgical removal of the tumor, without postoperative radiotherapy. METHODS The operation was performed via a frontopterional approach in 112 cases and a transsphenoidal approach in 10 cases. The tumor removal was considered total in 59%, subtotal in 29%, and partial in 12%. The surgical mortality rate was 2.5%. Even when tumor removal was not complete, radiotherapy was not systematically administered; it was reserved for cases of recurrence. The authors have studied clinical signs, operative characteristics, and ophthalmological, endocrinological, and functional outcomes, as well as recurrence risk and long-term patient survival. The mean follow-up period was 7 years. The functional results in these patients were excellent in 85%, good in 9%, fair in 5% (usually because of ophthalmological sequelae), and poor in 1%. Tumors recurred in 29 patients, but the salvage treatment, by operation or radiotherapy, was successful in 83%. The actuarial patient survival rate was 92% after 5 years and 85% after 10 years. CONCLUSIONS These results compared favorably with the data reported in the literature, suggesting that radical surgery of craniopharyngiomas allows good outcome in terms of survival, full recovery, and quality of life for both adults and children.

Abstract
From February 1994 to June 1999, there were 36 patients who underwent microsurgical resection for craniopharyngiomas. Of6 adult patients, large tumours (>4 cm) with extension from intrasellar or parasellar space to the foramen of Monro were found. There were 4 male and 2 female patients with ages from 18 to 44 years (mean 32.4 years). All of them underwent one-stage interhemispheric transcallosal total exc ision of tumours. This approach affords good overhead view of tumours and surrounding structures.Preoperatively, decreased visual acuity and restriction in the visual field was found in 5 patients. Studies of anterior pituitary function revealed far below the normal range in all patients. Polyuria was noted in 4 patients. All of 6 patients showed abnormally high levels of blood cholesterol and triglyceride and 4 patients were obese. Tumours with extension into the pituitary fossa were found in 2 cases. A relatively caudal location in the third Ventricle was found in case 6, who showed better preoperative visual function and no polyuria. There were no major surgical complications encountered. One patient with high cholesterol (731 mg%) died of acute pancreatitis 6 months after surgery. For large craniopharyngiomas without pre-chiasmatic extension, proper treatment could be achieved under substitution therapy and one stage transcallosal total excision of tumours with preservation of important neural structures.

Abstract
PURPOSE Intracranial tumors may cause eye misalignment and interruption of sensory fusion. The ocular misalignment may be permanent or may be corrected after tumor treatment with or without specific strabismus treatment. This report analyzes the binocular vision outcome of children with misaligned eyes from brain tumors who regain orthotropia. DESIGN A retrospective noncomparative case series. PARTICIPANTS Twenty-three surviving children less than 18 years of age with a new heterotropia and absence of fusion associated with the development of a brain tumor. INTERVENTIONS Tumor resection/radiation/chemotherapy and necessary strabismus management. MAIN OUTCOME MEASURE Stereopsis (>/= 4 of 10 circles) measured with the Randot II stereo test at near fixation. RESULTS Fourteen children regained orthotropia either after tumor therapy, strabismus treatment, or both. Ten of these 14 children with realigned vision regained high-grade stereovision. Nine patients did not regain orthotropia and were excluded. The mean age at tumor diagnosis of the fusing group was 9.9 years (range, 3-17 years) compared with 8.5 years (range, 6-12 years) in the four realigned nonfusing patients. The mean duration of misalignment was 12 months (range, 2-51 months) for the fusing group, and 45 months (range, 14-120 months) for the nonfusing group. CONCLUSIONS Children and adolescents with brain tumor-associated eye misalignment may regain the ability to fuse if their misalignment can be corrected. An improved prognosis was noted for those patients when the misalignment had been present for a shorter duration. These data suggest that the outcome may be better for incomitant strabismus than that reported for acute comitant esotropia.
