Multiple intracranial meningiomas are a condition where there is more than one meningioma in several intracranial locations in the same patient without signs of neurofibromatosis. Incidence varies from 1 to 10%. The prognosis of multiple intracranial meningioma does not differ from benign solitary meningiomas despite the multiplicity. However, the simultaneous occurrence of different grades of ...

Apart from calvarial infiltration, intracranial involvement in multiple myeloma is uncommon. Diffuse leptomeningeal invasion with or without parenchymal involvement is most common. Dural infiltration without involvement of the parenchyma, leptomeninges or skull is rare. The differential diagnosis of a dural plasmacytoma includes meningioma, which has a similar MRI appearance, metastasis, lympho...

Three cases of multiple spinal canal meningiomas are presented, bringing the total number of documented cases in the American literature to nine. While the exact incidence of multiple spinal meningiomas is difficult to determine, their possible occurrence warrants careful myelographic examination of the whole spinal canal, particularly if multiple clinical levels are present. When a complete bl...

Dr. Raphael Vicente Alves – Rua Estado de Israel 907 / 31 04022-002 São Paulo SP Brasil. E-mail: [email protected] Co-existing fibrous dysplasia and meningothelial meningioma is extremely rare. A search at “PubMed” (U.S. National Library of Medicine) with terms “fibrous”, “dysplasia” and “meningioma” demonstrated a total of 7 cases reported. Three cases in association with McCune-Albri...

The magnetic resonance (MR) appearance of intracranial meningioma typically is of an extraaxial mass that enhances intensely after contrast injection (1–3). However, difficulty in differentiating a meningioma from other processes can occur because of the tumor’s location or other features (1–5). En plaque meningioma can be difficult to image and can simulate other lesions, especially when near ...

Chordoid meningioma, classified as atypical meningioma according to the World Health Organisation (WHO) classification, is a rare subtype, which represents only 0.5% of all meningiomas and is associated with a high incidence of recurrence. Multiple intracranial meningiomas are rare in non-neurofibromatosis patients. We present a female patient with both of these rare types of meningioma. The pa...

The clinical features of a family with inherited multiple meningiomas as the major manifestation of neurofibromatosis are presented. The value of noninvasive radiological screening investigations is emphasised. The results of cytogenetic and pathological studies on the family are presented and discussed with a review of the relevant literature.

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...

Meningioma is a common pathology in the central nervous system (CNS). It arises from the arachnoid cap cells of the arachnoid villi in the meninges, which envelop the brain and spinal cord. Therefore, a meningioma can occur anywhere from the vertex to the spine. It is often named according to its anatomical location. For example, a meningioma abutting the sphenoid bone between the frontal and t...
