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.
PatientsTen 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.
ResultsSeven tumours were located in the right ventricle (70%) ranging in size from 2–8cm, with 7 tumours larger than 3cm in diameter. Nine patients underwent surgery with total excision in 8 cases and subtotal in the other; the remaining patient only received radiosurgery.
ConclusionsTotal resection is the gold standard for treatment which was possible in all but one of the cases undergoing surgery.
Los meningiomas intraventriculares son neoplasias poco frecuentes que constituyen alrededor del 2% de todos los meningiomas intracraneales.
Pacientes y métodosRevisamos 10 pacientes (6 mujeres, 4 varones; media de edad: 41.6 años) diagnosticados en nuestro servicio de neurocirugía entre 1978–2005 de meningioma de ventrículo lateral.
ResultadosEl 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 8cm.; 7 tumores tenían más de 3cm. 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.
ConclusionesLa resección completa es el tratamiento idóneo en los meningiomas intracraneales, que exceptuando un caso fue posible en todos nuestros pacientes operados.
