Clinical and Radiological Characteristics of Angiomatous Meningiomas
BACKGROUND Angiomatous meningioma is a rare histological subtype of meningioma. Therefore, this specific medical condition is rarely reviewed in the literature. In the present work, we report the clinical and radiological features with postoperative outcomes of angiomatous meningioma. METHODS This retrospective study included the patients who were pathologically diagnosed with angiomatous men...
متن کاملMicrocystic Meningioma - Unusual Variant of Meningiomas
Meningiomas are common benign tumors accounting for 13% to 18% of intracranial neoplasms. They are generally known to be solid tumors and their classical appearance on the computed tomography(CT) scan and magnetic resonance(MR) image usually lead to a correct diagnosis. Meningiomas have been subdivided into a variety of types, including meningotheliomatous, fibrous, transitional, psammomatous, ...
متن کاملDifferentiation of Benign Angiomatous and Microcystic Meningiomas with Extensive Peritumoral Edema from High Grade Meningiomas with Aid of Diffusion Weighted MRI
OBJECTIVE To determine whether angiomatous and microcystic meningiomas which mimic high grade meningiomas based on extent of peritumoral edema can be reliably differentiated as low grade tumors using normalized apparent diffusion coefficient (ADC) values. METHODS Preoperative magnetic resonance imaging (MRI) of seventy patients with meningiomas was reviewed. Morphologically, the tumors were d...
متن کاملGenomic landscape of meningiomas.
Meningiomas are one of the most common adult brain tumors. For most patients, surgical excision is curative. However, up to 20% recur. Currently, the molecular determinants predicting recurrence and malignant transformation are lacking. We performed retrospective global genetic and genomic analysis of 85 meningioma samples of various grades. Copy number alterations were assessed by 100K single-...
متن کاملSurgical Treatment of Intraspinal Angiomatous Meningiomas from a Single Center
Intraspinal angiomatous meningiomas (AMs) are rare lesions, and no case series have been reported. We retrospectively reviewed the data of 12 patients with intraspinal AMs. All patients underwent magnetic resonance imaging (MRI) of the spine. Computed tomography angiography was performed for three cases with cervical lesion. The series included six females and six males with a mean age of 49.6 ...
