A65-year-old man was admitted because of the progressive onset of left faciobrachiocrural paresis. Twenty years previously, he underwent a right nephrectomy for renal cell carcinoma; initial diagnosis was made by CT scan, because of the onset of hematuria; after nephrectomy, no adjuvant therapy was made. Brain MRI showed an extra-axial lesion of the falx, suspicious for meningioma (figure 1). T...

Download pose: Meningiomas are the most common central nervous system tumors in the population of age d older. WHO defines three grades predictive of the risk of recurrence. Clinical data supporting ogic malignant progression of meningiomas are sparse and underlying molecular mechanisms t clearly depicted. erimental Design: We identified genetic alterations associated with histologic progressio...

Malignant and atypical meningiomas are resistant to standard therapies and associated with poor prognosis. Despite progress in the treatment of other tumors with therapeutic vaccines, this approach has not been tested preclinically or clinically in these tumors. Spontaneous canine meningioma is a clinically meaningful but underutilized model for preclinical testing of novel strategies for aggre...

INTRODUCTION: Automatic segmentation and classification of brain tumors help in improvement treatment which will increase the life patient. Tumor may be noncancerous (benign) or cancerous (malignant). Precancerous cells also form into cancer.OBJECTIVES: Hough CNN is applied for selected section applies hough casting technique segmentation. METHODS: A multistage methodof extracting features, wit...

-Glial fibrillary acidic protein (GFA) was assayed in nerve-tumour extracts and located in these tumours by indirect immunofluorescence study. We conclude that GFA is a specific marker of both malignant and normal astrocytes. Non-astrocytic tumours (oligodendroglioma, meningioma) do not contain GFA. Tumours with astrocytic differentiation potential (medulloblastoma) may contain GFA. Comparison ...

A 13-year-old Spanish Breton was presented for a hyperacute onset of dull mentation followed by generalised tonic-clonic seizure and recumbency. An intracranial magnetic resonance imaging study identified well-demarcated intraventricular mass, cerebrospinal fluid analysis revealed moderate neutrophilic pleocytosis proteinorrachia. tentative diagnosis meningioma made medical treatment started. A...
