ABSTRACT
Von Hippel-Lindau (VHL) is a multi-system disease which results in significant morbidity from central nervous system (CNS) involvement as well as ocular, renal and neuro-endocrine effects. Haemangioblastomas of the CNS present a number of challenges. The natural history of these lesions is varied, as is the size and location within the CNS. Whilst surgery is considered the mainstay of treatment and best chance at curing these lesions, this is also often associated with significant risks due to the anatomical location of these lesions, most commonly the posterior fossa and spinal cord.We review the literature and describe our experience across two separate European VHL referral centres. Alternative treatment options and combined modalities are increasingly being used in the context of managing CNS haemangioblastomas. We analyse the increasing use of stereotactic radiosurgery and the evolution of medical treatments as potential future adjuncts to surgery. The availability of multiple modalities in our armamentarium is essential in tailoring a personalised treatment approach to these patients. Owing to the multi-systemic nature of the disease, in our experience, managing the care of patients with VHL is best delivered using an interdisciplinary approach utilising multiple specialties and adopting an individually tailored holistic approach.

BACKGROUND: The optimal management of clinoidal meningiomas (CMs) continues to be debated. METHODS: We constituted a task force comprising the members of the EANS skull base committee along with international experts to derive recommendations for the management of these tumors. The data from the literature along with contemporary practice patterns were discussed within the task force to generate consensual recommendations. RESULTS AND CONCLUSION: This article represents the consensus opinion of the task force regarding pre-operative evaluations, patient's counselling, surgical classification, and optimal surgical strategy. Although this analysis yielded only Class B evidence and expert opinions, it should guide practitioners in the management of patients with clinoidal meningiomas and might form the basis for future clinical trials.

BACKGROUND: The optimal management of petroclival meningiomas (PCMs) continues to be debated along with several controversies that persist. METHODS: A task force was created by the EANS skull base section along with its members and other renowned experts in the field to generate recommendations for the management of these tumors. To achieve this, the task force reviewed in detail the literature in this field and had formal discussions within the group. RESULTS: The constituted task force dealt with the existing definitions and classifications, pre-operative radiological investigations, management of small and asymptomatic PCMs, radiosurgery, optimal surgical strategies, multimodal treatment, decision-making, and patient's counselling. CONCLUSION: This article represents the consensually derived opinion of the task force with respect to the management of PCMs.

Coexistence of aneurysms and brain tumors is a rare occurrence. Coincidence is highest in patients with meningiomas rather than other types of tumors. We report a case in which a meningioma of the left anterior clinoid process was coexisting with a right middle cerebral artery (MCA) and a left anterior cerebral artery (ACA) aneurysm. While the right MCA aneurysm was detected preoperatively, the left ACA aneurysm was not detectable, being concealed by the major finding of the region. This report focuses on pitfalls of diagnosis and questions the surgical planning in aneurysms concealed by coincidental brain tumors.
