Jun 26, 2023 · The most common lesions at the CPA are vestibular schwannoma, meningioma, and epidermoid. Treatment options include observation, radiosurgery, and microsurgery. This activity reviews the evaluation and management of cerebellopontine angle tumors and reviews the role of the interprofessional team in improving care for patients with this condition.

Our study unexpectedly indicated that peritumoral brain edema is a risk factor for IAC involvement by CPA meningioma. Peritumoral brain edema around meiningiomas is vasogenic. While vascular endothelial growth factor is known to play a very important role in edema formation [ 25 ], the underlying mechanisms are poorly understood [ 26 , 27 ] and ...

Dec 10, 2024 · Cerebellopontine angle (CPA) masses are relatively common. Although a diverse range of pathologies may be seen in this region, the most common by far is vestibular schwannoma. Pathology. Cerebellopontine angle masses can be divided into four groups, based on imaging characteristics: enhancing mass. mass with high T1 signal on MRI

Cerebellopontine angle (CPA) meningiomas constitute about 1% of intracranial meningiomas. The clinical aspects of a series of 32 patients with surgically confirmed CPA meningiomas are analyzed. The most common symptoms at the time of the initial evaluation were from the eighth cranial nerve (unilate …

Apr 7, 2015 · Among intracranial meningiomas, 5%–10% are located in the cerebellopontine angle (CPA) [2, 3], thus comprising the second most common tumors in this anatomic region . Although enlargement and involvement of the internal auditory canal (IAC) is a common sign of schwannomas of the CPA [2, 4], these features can also be seen in meningioma ...

Jan 22, 2016 · MENINGIOMA. Meningiomas arise from meningothelial cells, also known as arachnoid cap cells, and are the most common nonglial primary neoplasms of the central nervous system (CNS). They are the second most common lesion in the CPA after schwannomas.

Nov 1, 2024 · Background and objectives: Cerebellopontine angle (CPA) meningiomas present challenges given their proximity to neurovascular structures. Postoperative complications and persistent symptoms can debilitate patients, and our ability to …

Cerebellopontine angle (CPA) meningioma represents about 5–10% of all CPA lesions. Sudden onset presentation of ataxia is unusual for CPA meningioma since most cases present with slowly progressive symptoms. Here, we present a cerebellopontine angle meningioma in a patient who presented as acute cerebrovascular accident.

Mar 1, 2020 · WHO grade II meningiomas of the CPA are exceedingly rare entities. In cases where patients present with a rapidly growing CPA mass, this should be considered in the differential diagnosis. The literature supports the notion that complete resection, when possible, is the strongest determinant of overall control.

Aim: To present our series of cerebellopontine angle (CPA) meningiomas, and to provide some innovative surgical steps for safe removal of these tumors. Material and methods: The clinical, radiological, and surgical characteristics of 32 patients with meningioma in the CPA were retrospectively analyzed.
