OBJECTIVE Malignant meningioma is rare and classified as Grade III in the WHO classification of CNS tumors. However, the presence of estrogen receptor (ER) in WHO Grade III meningiomas and its correlation with patients' outcomes are still unclear. In this single-center cohort study, the authors analyzed clinical features, treatment, and prognosis of these malignant tumors in patients with long-term follow-up. METHODS A total of 87 patients who were pathologically diagnosed with WHO Grade III meningiomas between 2003 and 2008 were enrolled in this study and followed for at least 7 years...

The Japanese population features the highest rate of elderly individuals worldwide. Moreover, Japan has the highest number of computed tomography/magnetic resonance imaging devices in the world, which has led to an increase in the incidental detection of meningioma in healthy elderly patients. Many previous papers have discussed the risks and indications for surgery in this patient population, but available information remains insufficient, and the definition of "elderly" has not been standardized. This review tried to clarify the published evidence and challenges associated with elderly meningioma based on a search of the PubMed database using the terms "meningioma," "elderly," and "surgery" for English-language clinical studies and collected related papers published from 2000 to 2016...

BACKGROUND: Intracerebral aneurysms co-existing with meningiomas are rare. Treatment strategies for intracerebral aneurysms co-existing with meningiomas have not yet been established. METHODS: We studied 62 patients with intracerebral aneurysms co-existing with meningiomas in the literature including our seven cases, evaluated the various managements and outcomes, and discussed the strategy for intracerebral aneurysms, especially unruptured cases, co-existing with meningiomas...

We report a case of fibrous meningioma with tyrosine-rich crystalloid in the frontal lobe of a middle-aged woman. The patient presented with a history of several years of worsening headaches and blurry vision, which progressed to include syncopal episodes and right-sided weakness. Imaging demonstrated a dural-based extra-axial mass arising from the right orbital roof and extending superiorly along the right frontal convexity causing right-to-left midline shift. The patient underwent a craniotomy and operative resection...

BACKGROUND: Meningioma is the commonest primary intracranial tumour in adults. Excision is curative for low grade meningioma, whereas high-grade meningioma requires adjuvant therapy following surgery. Several studies have examined the association between peritumoural brain Edema - a common feature in meningioma - and histological grading with mixed results. The present study attempted to elucidate this association and if peritumoural brain Edema affects the intra-operative judgement of surgeons on the completeness of resection...

Trigeminal trophic syndrome (TTS) is a condition whereby persistent facial ulceration presents consequent to central or peripheral insult to the trigeminal nerve. Lesions are created by repetitive self-inflicted manipulation and trauma of dysaesthetic skin within the trigeminal dermatome. We discuss four cases with aetiologies varied from presumed microvascular compromise to resection of cerebral meningioma, cerebrovascular accident, and herpes zoster ophthalmicus. We discuss the management of the under-recognised associated periocular skin ulcerations that result from physical manipulation of dysesthic skin and prove to be persistent and challenging to treat...

Optic nerve sheath meningiomas (ONSM) and intra-conal orbital lymphomas are common entities on the differential of a retrobulbar optic nerve involving space-occupying lesion. In this study, we compare the pre-surgical diagnosis, based on clinical presentation and neuroimaging, to the surgical pathology results of intra-conal orbital lymphomas and ONSM. This is an IRB approved retrospective chart review of orbital lymphomas and optic nerve sheath meningiomas biopsied by a single surgeon over a 4-year period at a single institution...

REVIEW

Extra-axial tumors are intracranial neoplasms but are not located within the brain parenchyma. The localization of intracranial neoplasms helps to narrow down the possible differential diagnoses and also plays a deciding role in the treatment strategy and the prognosis. For this reason exact localization of these lesions is extremely important. Extra-axial tumors are the most common neoplasms among adults. They can be divided in a broad spectrum of histopathological subgroups. The most common extra-axial tumors are meningiomas, which arise from the dura mater...

In 5000 BC, South American tribes digged the bones in the living head to seek ways to communicate with the gods, which was primitive trephination and may be the first neurosurgical behavior. In 2600 BC, Imhotep in ancient Egypt took the brain out of the head from the nose, for a better preserve of the mummy, which was a prototype of modern transsphenoidal surgery. And the development of anatomy in ancient Greek laid a solid foundation for neurosurgery. From 500 to 1500 AD, the rise of religion and the occurrence of war, prompted a large number of craniocerebral trauma, which contributed greatly to the early development of neurosurgery as a distinct specialty...

Purpose To investigate the association between exposure to head computed tomography (CT) and subsequent risk of meningioma. Materials and Methods The study was approved by the local ethics committee. A cohort of 26 370 subjects was retrospectively collected from a radiology archive of CT examinations of the head performed from 1973 through 1992. For comparison, an age- and sex-matched cohort of 96 940 subjects who were not exposed to CT (unexposed cohort) was gathered. The risk of meningioma was assessed by using data from the Swedish Cancer Registry; however, one-third of patients with meningioma had to be excluded because they either had a prevalent meningioma or other brain tumor at the first CT examination or had undergone radiation treatment to the head...

REVIEW
Siba El Hussein, Cristina Vincentelli
Pituicytoma is a rare low-grade glial neoplasm that originates in the distribution of the neurohypophysis, including the posterior pituitary lobe and infundibular stalk. The tumor cells resemble pituicytes, which are specialized glial cells of the neurohypophysis. Pituicytoma can be misdiagnosed pre-operatively as a pituitary adenoma due to overlapping clinical and neuroimaging features between these two entities. Pituicytoma can also mimic other neoplasms of the sellar and parasellar regions microscopically - meningioma, schwannoma and pilocytic astrocytoma - and shares immunohistochemical expression of TTF-1 with spindle cell oncocytoma and granular cell tumor of the sellar region, suggesting a common histogenesis...

We report a woman with multifocal lesions suggestive of meningiomas in MRI, which also presented with high Ga-DOTATATE uptake in PET, a finding characteristic for meningioma. A whole-body staging due to a pathological fracture revealed multiple neoplastic lesions throughout the body without detection of a primary site. Subsequent pathological workup of a lung lesion revealed multifocal metastases from follicular thyroid cancer despite thyroidectomy 10 years ago (without pathological finding), and posttreatment scans after radioiodine therapy confirmed the multiple brain lesions to be metastases as well...

In children with newly diagnosed acute myeloid leukaemia (AML), myeloid sarcomas (MS) of the central nervous system (CNS) are rare. Since MS involving the CNS are potentially curable, timely recognition is paramount. Establishing a diagnosis may be problematic as they can easily mimic primary CNS neoplasms. We report the case of a 5-year-old boy with AML with t(8;21)(q22;q22) rearrangement who presented with a massive intracranial MS and rapid clinical deterioration suggestive of a meningioma or a primitive neuroectodermal tumour...

We describe the importance of collaboration between multiple surgical specialties in managing a complex case of sight-threatening severe proptosis in a young woman with type 2 neurofibromatosis (NF2) complicated by pre-existing contralateral blindness. Trans-nasal and lateral orbital surgical approaches were aided by stereotactic navigation to debulk a large frontal/sphenoid wing meningioma, which had been exerting pressure onto the right globe and optic nerve. The patient made an excellent postoperative recovery along with preserved residual visual acuity, normal neurology and a good aesthetic outcome...

BACKGROUND: Rhabdoid meningioma (RM) is an unusual variant of meningioma, classified as WHO grade III. Although its recurrence is common, extracranial metastasis is rare and usually misdiagnosed. The transfer mechanism and pathway are ambiguous; once it develops, there is a poor prognosis and no effective management. The present case is the first report on concurrent intracranial and pulmonary RM with rapid and widespread metastasis. We hope this report can be a helpful reference for clinicians and radiologists...

INTRODUCTION: Advances in radiological imaging techniques have enabled volumetric measurements of meningiomas to be easily monitored using serial imaging scans. There is limited literature on the relationship between tumour growth rates and the WHO classification of meningiomas despite tumour growth being a major determinant of type and timing of intervention. Volumetric growth has been successfully used to assess growth of low-grade glioma; however, there is limited information on the volumetric growth rate (VGR) of meningiomas...

Cancer is not a single disease. The term refers to literally hundreds of illnesses sharing common features: inappropriate proliferation of imperfectly differentiated cell types, invasion of nearby vital structures, and spread to distant sites (metastasis). Invasiveness and metastasis distinguish cancers from benign tumors such as fibroids and meningiomas. Yet, each type is distinct, possessed of defining morphologic, histologic, biochemical, and genomic features that have allowed oncologists to develop a nosology that guides diagnosis and therapy...
