“…Sixteen patients revealed further cranial nerve deficits, including Cranial Nerves III (n ϭ 4), IV (n ϭ 4), V (n ϭ 2), VI (n ϭ 2), and VIII (n ϭ 2), and unspecified diplopia (n ϭ 6) ( Table 2). Five patients harbored multiple meningiomas in terms of a meningiomatosis (30), and three patients had bilateral SOMs (Fig. 4).…”

Complete surgical resection of SOMs is frequently impossible because the involvement of delicate structures of the orbital cone is common. Although some persisting neurological deficits are possible, proptosis and other visual deficits are often relieved. Two-thirds of tumor rests remained stable during the follow-up period. Consequently, the surgical aim should be the relief of leading symptoms rather than radical resection.

“…Every tumor should be approached on a case by case basis, and just the presence of multiple tumors does not justify their removal. 11,12 Since it is well documented that multiple intracranial meningiomas are histologically benign, the prognosis is good and the same as for solitary meningiomas. 10 Nakamura et al reported the annual growth rate from 0.73 to 1.67 cm 3 per year and the tumor doubling time from 1.19 to 6.81 years.…”

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 more predominantly. CASE PRESENTATION:We report 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 sensorineural hearing loss (SNHL), hence NF-2 was ruled out. The patient was successfully operated upon by parietal craniotomy using the interparietal sulcus approach, and complete excision of the intraventricular tumor was done. Postoperatively, the 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:Multiple meningiomas 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.

“…These tumors frequently develop in the third ventricle and supratentorial regions, such as the parietal, temporal, and occipital lobe [ 1 ]. Multiple meningiomas represent two or more meningiomas in the same patient, separated by anatomical location [ 6 ]. Three theories have been proposed to account for the etiology and pathogenesis of multiple meningiomas: multicentric dural foci; metastasis by blood-borne spread; and metastasis by the cerebrospinal fluid.…”

“…Unlike canine meningiomas, feline intracranial meningiomas are usually benign, fibrotic, and well encapsulated, and surgical excision is the standard treatment [ 1 , 5 ]. In the case of multiple meningiomas, which have characteristics similar to solitary meningiomas, the number of meningiomas does not have a significant effect on the survival and outcome of surgery if they have been assessed correctly and surgical resection has been performed thoroughly [ 2 , 6 ]. However, surgical resection of multiple meningiomas is associated with complications; complicated surgical plan, prolonged surgical time, intraoperative hemorrhage, and limited surgical space leading to brain parenchymal traction injury [ 8 , 10 ].…”

A 13-year-old castrated male domestic shorthair cat was referred for the surgical removal of multiple meningiomas. The cat experienced generalized tonic–clonic seizures, altered mentation, mild proprioceptive ataxia, and circling. Magnetic resonance imaging (MRI) revealed two round, solitary, well-delineated, space-occupying lesions suggestive of multiple meningiomas in the right frontal and occipital lobes. Before surgery, patient-specific three-dimensional (3D) printed models and guides were produced using a 3D program based on MRI and computed tomography (CT), and a rehearsal surgery was performed. With a 3D guide to find the location of the craniotomy lines, bilateral extended rostrotentorial craniotomy allowed en bloc resection of multiple meningiomas. The bone fragment was replaced and secured to the skull with a craniofacial plate and screws with an artificial dura. All of the surgical steps were performed without complications. The preoperative presenting signs were resolved by the time of follow-up examinations 2 weeks after surgery. Twelve months after the removal of the multiple meningiomas, the cat survived without further neurological progression. For the resection of multiple meningiomas, surgery can result in large bone defects and risk of massive hemorrhage. For this challenging surgery, patient-specific 3D models and guides can be effective for accurate and safe craniotomies.
