OBJECTIVES To present our experience in operated meningioma cases regarding their prevalence, anatomical location, multiplicity, presenting signs and symptoms, and the possible correlation between MRI signal intensity and histological grades to set criteria for radio-pathological diagnosis. METHODS In this retrospective study, operated meningioma cases in the Department of Neurosurgery, Jorda...

Introduction  Pneumosinus dilatans (PSD) is a rare phenomenon involving the expansion of the paranasal sinuses, without bony destruction or a mass. Previously documented cases have demonstrated simple expansion of a solitary air cell. We present two unique cases of PSD in the presence of meningioma, in which complex new cells developed within the frontal sinus. One of the two patients developed...

The present study describes a case of a solitary fibrous tumor (SFT) concurrent with meningioma in the same anatomical region. The patient was admitted to Tianjin Huanhu Hospital (Tianjin, China) presenting with progressive eyesight impairment, dizziness and right hemiparesis. Cranial magnetic resonance imaging revealed two primary tumors co-occurring at the same site. One lesion was a solid le...

Introduction: The primary and definitive diagnosis of meningioma is based on histological assessment; however, employing imaging methods, like Magnetic Resonance Imaging (MRI) is very helpful to describe lesion’s characteristics. Accordingly, we decided to study the effect of imaging factors, like MRI data on the volume of hemorrhage (estimated blood loss) during meningioma surgery. Methods: T...

OBJECT This study was undertaken to test a hypothesis that meningiomas of the midline skull base and spine are predominantly of the meningothelial histological subtype. METHODS The cases of 794 consecutive patients who underwent resection for meningioma at the Cleveland Clinic between January 1991 and March 2004 were reviewed retrospectively. The authors analyzed the relationship between the ...

Meningioma is well known as common disease of the central nervous system, whereas primary extracranial meningioma is rare, representing 1% to 2% of all meningiomas. We have experienced a case of primary extracranial meningioma presenting as a right cheek mass. The tumor was completely excised via a right lateral rhinotomy incision. Histopathologic examination confirmed the diagnosis of primary ...

Meningioma is the commonest primary intracranial tumor in adults, with majority being benign. Malignant meningioma exceedingly rare and carries a poor prognosis because of its tendency for local recurrence distant metastasis. We present case 53 years old male anaplastic malignant meningioma, which recurred after excision radiotherapy later metastasised to pleura, bones brain. Keywords: Metastat...

abstract neurofibromatosis 1 (nf1) an autosomal dominant disorder, is the most common of the phakomatoses (neurocutaneous syndromes) and has a variety of localized or systemic manifestations and the classic systemic lesions include neurofibromas and more specifically, plexiform neurofibromas. a 60-year-old female presented with a progressively increasing swelling over left side of forehead and ...

BACKGROUND S-100B protein is an established serum marker of primary and secondary brain damage in head injury and stroke. Despite major progress in neurophysiologic monitoring, there are still difficulties in the early identification and quantification of evolving edema or trauma after craniotomy for tumor. In this study we aimed to correlate serum S-100B values with early postoperative neurolo...

OBJECTIVE Anecdotal evidence suggests that radiosurgical ablation of parasagittal meningiomas may be associated with increased risk of subsequent edema. Potential predictors of postradiosurgical peritumoral edema, including parasagittal tumor location, tumor size, and treatment dose, were evaluated. METHODS We retrospectively reviewed records of 102 patients with 111 supratentorial meningioma...
