Resumen
Introducción

Los tumores intraventriculares representan alrededor del 10% de los tumores del sistema nervioso central. Los schwannomas intraventriculares son infrecuentes y solo existen 15 casos descritos en la literatura.

Caso clínico

Paciente de 41 años de edad, con antecedentes de migrañas de 17 años de evolución, que consultó por cefaleas y náuseas. La tomografía y resonancia magnética de cerebro evidenciaron una lesión nodular sólida a nivel del asta occipital derecha con realce homogéneo con contraste. Se realizó una exéresis completa a través de una craneotomía parietal y un abordaje transcortical. La evolución postoperatoria fue favorable. La anatomía patológica informó: schwannoma. La resonancia de control a los 18 meses no mostró recidiva.

Conclusión

Los schwannomas intraventriculares son lesiones muy infrecuentes. El tratamiento quirúrgico de elección es la resección completa. Es un diagnóstico a tener en cuenta en tumores intraventriculares.

Summary
Introduction

Intraventricular tumors account for approximately 10% of central nervous system tumors. The intraventricular schwannomas are rare because there are only 15 cases reported in the international literature.

Case report

A forty-one years old female, with a history of migraines during 17 years, consulted for headaches and nausea. Brain computed tomography and magnetic resonance imaging evidenced solid nodular lesion at the right occipital horn with homogeneous contrast enhancement. Complete excision was performed through a right parietal craneotomy and a transcortical approach. The postoperative evolution was favorable. The pathology report: schwannoma. The magnetic resonance imaging 18 months after resection showed no recurrence of tumors.

Conclusion

Intraventricular schwannomas are very rare tumors. Surgery is treatment of choice for total resection. This is a diagnosis to consider in intraventricular tumors.
