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.

The authors present the case of a 62-year-old woman with rapid enlargement of a meningioma following radiosurgery (RS). Previous slow growth of the tumor over a 3-year period and the radiological signs of benign meningioma had been confirmed by successive MR scans. Histopathological examination performed after successful surgical removal revealed an atypical, infiltrating meningioma.

Pneumosinus dilatans (PSD) refers to an abnormally enlarged, air-filled paranasal sinus without radiological evidence of localized bone destruction, hyperostosis, or mucous membrane thickening. This disorder has been associated with meningioma, especially optic nerve sheath meningioma, but its pathophysiology remains unclear. Spontaneous pneumocephalus is an exceptional presentation of PSD and,...

PURPOSE Molecular and clinical observations suggest a role of sex steroid hormones in the occurrence of meningioma. However, there is limited and often conflicting data on the use of hormone replacement therapy (HRT) as a possible risk factor for meningioma. The goal of this study was to investigate whether there is an association between a diagnosis of meningioma and either current or past HRT...

We reported a 71 years old woman, with history of rest and postural tremor, bradykinesia and memory problems. In her dynamic MRI, a contrastenhanced tumor in the cerebellopontine (CP) angle was found which was compatible with a meningioma. 99mTc-TRODAT SPECT showed decreased activity in the left putamen, indicating idiopathic Parkinson disease. There was also a focus of increased activity on th...

Meningioma of the internal auditory canal is very rare. There are only 15 previous reports of intracanalicular meningioma. The authors add a case report of a patient with meningioma of the internal auditory canal. A 31-year-old woman presented with a one-year history of headache, dizziness, hearing loss and left facial paralysis. An MRI of the temporal bone demonstrated a tiny isointense intrac...

Primary extradural meningioma is about 1-2% of all meningiomas. Primary intraosseous meningioma is a rare form of intra-bone tumors that account for approximately 67% of extradural meningiomas. We report a primary intraosseous meningioma of a 69-year-old man who had headaches and a mass on right parietal scalp for the past few months. Remarkably, the brain tissue within the osteolytic cavity of...
