Meningioma constitutes 27% of primary CNS tumours. It rarely metastasizes to distant sites (< 0.1%). Here, we present a case report of primary atypical intracranial meningioma metastasizing to liver and bone after 4 years of surgery and postoperative radiotherapy presenting with multiple episodes of hypoglycemia.
BACKGROUND The etiology of meningioma, the second most common type of adult brain tumor in the United States, is largely unknown. Prior studies indicate that history of immune-related conditions may affect the risk of meningioma. METHODS To identify genetic markers for meningioma in genes involved with innate immunity, we conducted an exploratory association study of 101 meningioma cases and ...
BACKGROUND The predominant treatment modality for meningioma is surgical resection. However, gamma knife radiosurgery is also an important treatment modality for meningioma that is small or cannot be completely removed because of its location. In this study, we evaluated the effectiveness and long-term results of radiosurgical treatment for meningioma in our institution. METHODS We studied 62...
normal 0 false false false en-us x-none ar-sa radiation therapies are commonly used for malignant or metastatic brain tumors for curative and palliative use. the radiation-induced neurotoxicity includes both parenchymal and vascular damage. here we report the case of a 43-year-old woman who developed multiple sclerosis (ms) 9 months after she underwent the last session of radiotherapy for the d...
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...
AIM To evaluate helical tomotherapy for the treatment of complex-shaped uni- or multifocal meningiomas. METHODS AND MATERIALS Between 2007 and 2009, 12 patients with complex-shaped meningiomas and/or multiple meningioma lesions were treated with helical tomotherapy. Histologic classification according to the most recent WHO classification for brain tumors was WHO grade I meningioma in 5 patie...
BACKGROUND Meningiomas account for up to 37% of all primary brain tumors. Genetic susceptibility to meningioma is well established, with the risk among relatives of meningioma patients being approximately threefold higher than that in the general population. A relationship between risk of meningioma and exposure to ionizing radiation is also well known and led us to examine whether variants in ...

DESCRIPTION A 65-year-old woman comes for headache management. Few years ago, she was diagnosed with a ‘single benign tumour of the anterior part of the brain’. A new contrast CT brain scan was done (figures 1 and 2); as she was claustrophobic, brain MRI was not ordered. The mass they have referred to was most likely a falcine meningioma. In addition, there is an oval hyperdense mass at the rig...
