Abstract

Background- Multiple Meningiomas (MMs) are defined as the presence of at least two lesions that appear at different intracranial locations, without the association of neurofibromatosis 2 (NF-2). They constitute 1-9 % of meningioma patients with females seen predominantly.
Case Presentation- Authors report here an unusual case of giant intraventricular meningioma with bilateral petrous meningiomas in a young female patient which gave a radiological impression of NF-2. Pure tone audiometry (PTA) was done which ruled out any sensori-neural hearing loss (SNHL). Hence NF-2 was ruled out. The patient was successfully operated by parietal craniotomy-interparietal sulcus approach and complete excision of the intraventricular tumor was done. Post-operatively patient had no new deficits. The patient was then followed up with Gamma Knife Surgery for the bilateral petrous meningiomas and anterior falcine meningioma.
Conclusion- MMs need to be differentiated from neurofibromatosis-2, which may alter management and prognosis. Every meningioma must be operated on its merit, irrespective of whether it is part of multiple meningiomatosis or not.
