Angiomatous Meningioma: CT and MR Imaging Features
giomas on computed tomography (CT) and magnetic resonance imaging (MRI) are easily identified and hence, easy to diagnose (1). However, certain meningioma subtypes have unusual imaging findings, making it difficult to diagnose them as well as determining the appropriate treatment protocol. This is particularly true for rare meningioma subtypes, which include the angiomatous meningioma, which sh...

متن کاملPrimary extradural intra-orbital meningioma in a Chinese girl.
PRIMARY intra-orbital meningiomas are rather uncommon, and primary intraorbital meningiomas unattached to the optic nerve sheath are decidedly rare. Scarpa (1816) was quoted by Byers (1901) as being the first to have reported an intraorbital meningioma. Goar (1926) and Mayer (1928) estimated the number of intra-orbital meningiomas in the literature at 40, but there was no clear indication in ma...
متن کاملBenign orbital angiomatous tumors with intracranial extension
Orbital neoplasms with associated bone erosions and intracranial extension are generally considered suspicious for malignancies. Here, we describe the clinical and radiological findings, as well as the surgical management of two extraordinary cases, in which such bony perforations with subsequent intracranial tumor growth resulted from benign angiomatous orbital neoplasms. Two female patients, ...
متن کاملIntradural angiomatous meningioma arising from a thoracic nerve root
BACKGROUND Spinal intradural meningiomas that arise purely from a nerve root without dural attachments are extremely rare. Spinal meningiomas arise from arachnoidal cap cells in the spinal canal, and growth of these tumors exerts pressure on the spinal cord and nerve roots. CASE DESCRIPTION A patient presented with a lesion at the T3-T4 level that resembled a schwannoma on magnetic resonance ...
