We report a case of tuberculum sellae meningioma with optic tract edema. Contrary to a prior report on this topic, edema along the optic tract is not only seen in craniopharyngiomas but may be seen (although rarely) in other common parasellar tumors, as in our case of a tuberculum sellae meningioma. The pathogenesis of this edema in meningioma is controversial.

We describe the rare entity of an intraosseous meningioma arising in the mandible. The meningioma was found incidentally in an asymptomatic adult patient on dental radiography, mimicking other cystic-appearing jaw masses. The CT and MR imaging features of mandibular meningioma are reviewed with reference to prior published descriptions of this unusual entity.

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 ...

Meningioma presenting as ischemic stroke is very rare. We report a case of left medial sphenoid wing meningioma with cerebral infarction due to occlusion middle artery (MCA) in 36-year-old female. discuss the incidence, pathophysiology, management and review literature intracranial stroke.

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...

BACKGROUND AND PURPOSE Imaging characteristics of temporal bone meningioma have not been previously reported in the literature. CT and MR imaging findings in 13 cases of temporal bone meningioma are reviewed to define specific imaging features. METHODS A retrospective review of our institutional case archive revealed 13 cases of histologically confirmed temporal bone meningioma. CT and MR ima...

INTRODUCTION Extra-cranial meningioma or ectopic meningioma is a rare tumor. This tumor has been reported in various anatomic sites in the head and neck, mediastinum, skin and soft tissues. We report a rare case of ectopic meningioma in the submandibular region detected by using fine-needle aspiration cytology, histopathology and immunohistochemistry. This case represents another unusual site f...

The widespread use of cellular telephones has generated concern about possible adverse health effects, particularly brain tumors. In this population-based case-control study carried out in three regions of Germany, all incident cases of glioma and meningioma among patients aged 30-69 years were ascertained during 2000-2003. Controls matched on age, gender, and region were randomly drawn from po...
