“…One of our patients, who rejected surgery, was treated using fractionated radiosurgery; although the efficacy of this treatment has not been established and there have as yet been few reports 37 . Reports of 85% to 98% tumour control rates achieved with radiosurgery cannot be overlooked during the informed consent procedure 28 .…”

SummaryBackground. Intraventricular meningiomas are rare tumours that represent about 2% of all intracranial meningiomas, and represent one of the most challenging problems in neurosurgery. They are located deep within the brain and often are sizable and highly vascular. We report on a series of 10 meningiomas of the lateral ventricles treated at our institution during the last 28 years.Patients. Ten patients (6 women, 4 men; mean age 41.6 yrs) were admitted to our medical center between 1978-2005 with meningioma of the lateral ventricles. Headache was the first symptom in 8 cases and ocular signs were present in 5 patients.Results. Seven tumours were located in the right ventricle (70%) ranging in size from 2-8 cm, with 7 tumours larger than 3 cm in diameter. Nine patients underwent surgery with total excision in 8 cases and subtotal in the other; the remaining patient only received radiosurgery.Conclusions. Total resection is the gold standard for treatment which was possible in all but one of the cases undergoing surgery. Resultados. El síntoma de debut fue la cefalea en 8 casos y en 5 pacientes existían alteraciones oculares. Siete tumores estaban localizados en el ventrículo derecho (70%) con un tamaño que oscilaba entre 2 y 8 cm.; 7 tumores tenían más de 3 cm. de diámetro. Se intervino quirúrgicamente a 9 pacientes consiguiéndose una extirpación completa en 8 casos y subtotal en el otro; el paciente restante fue tratado mediante radiocirugía estereotáctica.Conclusiones. La resección completa es el tratamiento idóneo en los meningiomas intracraneales, que exceptuando un caso fue posible en todos nuestros pacientes operados.PALABRAS CLAVE: Abordajes quirúrgicos.

Intraventricular meningiomas are rare tumors, comprising only 0.5% to 5% of all intracranial meningiomas. In this article, 8 cases of histopathologically proven intraventricular meningioma that were treated at the Ç ukurova University Neurosurgery Department are discussed. The radiologic, histologic, and clinical findings of intraventricular meningiomas and the surgical approach to lateral intraventricular meningiomas were reviewed retrospectively. Our 8 patients ranged in age from 18 to 65 years (mean = 44.6 years). Two patients were male and 6 were female, for a 1:3 male-to-female ratio. Computed tomography and magnetic resonance imaging demonstrated the 7 tumors within the lateral ventricle and only 1 tumor within the third ventricle. All lateral ventricular tumors were located in the region of the trigone. Headache and hemiparesis were the most common presenting symptoms. Histologic studies revealed meningotheliomatous meningiomas in 5 patients, transitional meningioma in 2 patients, and anaplastic (malignant) meningioma in 1 patient. The superior parieto-occipital approach in 5 patients, posterior middle temporal gyrus approach in 2 patients, and posterior transcallosal approach in 1 patient were used for surgical therapy, and total resection was achieved in all patients. The overall neurologic outcome at follow-up (mean follow-up = 12 months, range: 1 month to 5 years) was excellent (no deficit) in 4 patients, good (some deficit but independent) in 2 patients, and poor (dependent) in 1 patient. One patient died after surgery. We conclude that intraventricular meningiomas are curable by complete surgical resection. This is possible with little neurologic morbidity when the neurosurgeon understands the surgical approaches available and the indications for those approaches.

This 65-year-old man presented with a very rare malignant meningioma in the trigonum of the right lateral ventricle. Neurological examination showed bilateral papilledema. Magnetic resonance imaging revealed a solid, enhancing tumor in the right trigonum with a hypointense cystic component located in the center of the tumor. The lesion was totally resected via a superior parietooccipital transcortical approach. Histological examination showed an anaplastic (malignant) meningioma with architectural disarray, high mitotic activity (20/10 hpf), necrosis, and cytological atypism. As in our case, heterogeneous signal, due to necrotic tissue and frequently demonstrated on both T1- and T2-weighted sequences, is suggestive of an aggressive type of meningioma.
