The lectins Peanut agglutinin (PNA), Canavalia ensiformis (Con A), Ulex europaeus-1 (UEA-1), Dolichos biflorus (DBA), Triticum vulgaris (WGA) were studied in a series of 36 meningiomas (16 meningotheliomatous-including 3 recurrences, 7 transitional, 4 angiomatous, 2 "hemangiopericytic", 3 papillary-including 1 recurrence, 4 anaplastic-including 3 recurrences. PNA binds to all cases of meningoth...

The occurrence of meningiomas in children is rare, accounting for less than 5% of tumors of the central nervous system in childhood. This is a retrospective study of 10 patients with CNS meningiomas. The goal of this study was to determine the epidemiology, clinical and radiological features, and long-term outcome of meningiomas. The results ware compared with those reported in the literature.

AIM To assess the efficacy of the far lateral approach, without drilling of the occipital condyle, in the management of anterior intradural tumors at the craniocervical junction. MATERIAL AND METHODS Ten patients suffering from foramen magnum tumors were operated upon via the far lateral approach without drilling of the occipital condyle. All patients underwent postoperative C...

Meningioma accounts for approximately one-third of primary central nervous system tumors. Most meningiomas are benign, although up to one third are classified as atypical or malignant. We describe a 63-year Caucasian male presenting with pleural metastases from an intracranial meningioma. Distant metastases from meningiomas are infrequently found in clinical practice and mostly are associated w...

Meningiomas are typically benign, slowly growing tumors. Meningiomas of the spine are most commonly intradural, extramedullary lesions and account of 25% – 46% of all spinal cord tumors in adults (Peker et al., 2005). Approximately 80% of spinal meningiomas occur in the thoracic spine, followed in frequency by cervical and lumbar lesions (Helseth et al., 1989; Levy et al., 1982; Roux et al., 19...

Meningiomas are well-recognized tumors of the central nervous system. Extracranial meningiomas, secondarily extended into the paranasal sinuses, are rare tumors, comprising approximately 2% of all meningiomas. Extracranial meningiomas of the paranasal sinuses may present a diagnostic and the rapeutic challenge. We present a retrospective review comprising three cases and discuss the clinical pr...

Most intrasellar meningiomas are located in the subdiaphragmatic and supraglandular region because they originate from the diaphragma sellae. Subglandular meningiomas located under the pituitary gland are extremely rare. Intrasellar meningiomas in the subdiaphragmatic and subglandular region probably originate from the dura in the sellar floor. We report a case of a subglandular meningioma alon...

BACKGROUND Meningiomas are common brain tumours and display gender, racial and ethnic differences in their demographic profile. The demographic profile of our patients diagnosed with intracranial meningiomas is presented and compared with the literature. OBJECTIVES To determine the age, gender, racial and ethnic distribution of our patients diagnosed with intracranial meningiomas. METHODS C...

The goal of preoperative embolization of intracranial meningiomas is to facilitate their surgical removal by reducing tumor vascularity and decreasing blood loss during surgery. This study is based on personal experience with about 100 embolized meningiomas and on the experience of others. Embolization is performed during the same session as diagnostic angiography. The appropriate embolic mater...

BACKGROUND Determining factors that could accurately predict pathological features of meningiomas before histological diagnosis would help surgeons to proper balance the risk of operation and the resection grade. The aim of this study was to explore the potential risk factors for atypical (WHO Grade II) and anaplastic (WHO Grade III) meningiomas. METHODS Records of 1,239 patients between Janu...
