Background: Meningioma is among the most common slow growing central nervous neoplasms, which recurs locally despite the benign histologic features. The aim of this study was to evaluate osteopontin and ki67 expressions in different histologic grades of meningioma in a group of Iranian people. Methods: In this cross-sectional study, first, the paraffin blocks with the definite pathological dia...

Introduction: Meningioma is a benign and slowly-growing tumor that is responsible for 20% of brain neoplasms. It can be accompanied by some genetic disorders such as neurofibromatosis type 2 and is more common among women. As a space occupying lesion, it produces a wide range of signs and symptoms by compressing the adjacent and underlying tissues in the brain. Trauma and vi...

introduction many conditions can mimic psychiatric symptoms. amongst them, intracranial mass and space occupying lesions have a significant importance. aggression and hallucination are seen in association with a basal frontal lesion, and may mimic psychotic syndromes. case presentation a 37-year-old man with no previous mental illness presented with a month history of headache, blurred vision, ...

multiple primary tumors in a single patient are relatively rare when four or more distinct lesions are considered. herein, we report a case of woman with four different primary tumors: meningioma, renal angiomyolipoma, spinal ependymoma and high-grade soft tissue sarcoma. there was no family history and hereditary syndrome. the genetic analysis was completely normal. to best of our knowledge, t...

We report a case of intra-osseous meningioma of the skull in a 45 year old lady secondary to trauma, preoperatively suspecting it to be chronic osteomylitis. According to literature search only one case intra-osseous meningioma has been reported. Intra-osseous meningioma secondary to trauma has not been reported before.

Dumbbell growth is often observed in schwannoma but rarely in meningioma. In particular, the occurrence of dumbbell meningioma at the cervical cord level in Japan is markedly rare. We reported an elderly case with symptomatic meningioma that developed in a dumbbell shape from cervical spine and was treated successfully by surgery.

Meningioma is a common intracranial tumor in adults. Pediatric cases account for approximately 1.5% of all intracranial meningiomas, and very few cases show malignant histological features. Primary pediatric malignant meningioma in the cerebellopontine angle is extremely uncommon. Herein, we report a 2-year-old girl with malignant meningioma in the cerebellopontine angle. The clinical features,...

in this article, we report a 49-year-old woman with simultaneous meningioma and astrocytoma occurrence in the same patients without radiotherapy, phacomatosis, or any genetic disorders. we aimed to define surgical management and the etiopathogenic correlations of meningioma with glioblastoma.
