Abstract
Aim: Intraventricular meningiomas are rare tumors which were not covered sufficiently in the Czech literature. Presenting our retrospective study, the aim of this article is to introduce typical clinical presentation, diagnostics, surgical treatment and its complications to the reader.
Moreover, it provides a basic review of already published literature as well as it compares the achieved results with recently published series of international authors. Material and methods: Data of 19 patients who underwent surgery for intraventricular meningioma at our institution between 2002- 2015 were analyzed retrospectively, the average follow-up is 3 years and 5 months.
The average age in our cohort was 49 years. Women were affected 2.8 times more often.
The medical files, clinicoradiological findings, surgical interventions and their outcome were analyzed retrospectively. Results: The most common presenting symptom was headache (53%).
Most frequently (89%), meningiomas were located in the lateral ventricles. Usually, the surgery were performed using parietooccipital approach, radical resection was achieved in all patients.
Resolution of the previous symptoms and signs was achieved in 84% of patients. As for the permanent complications, the most often was epileptic seizure (11%), homonymous hemianopia (5%), and expressive phatic disorder (5%).
There was one recurrence in our serie (5%). Concerning the high potential surgical risk, the recurrence was irradiated with the Leksell gamma knife.
Conclusion: The gold standard of the therapy of symptomatic intraventricular meningiomas is the microsurgical resection. In the case of reccurence, stereotactic radiosurgery is as well an option.
The asymptomatic tumors could be observed. The factors increasing the surgical risk include higher age, comorbidities, size and location of the tumor and its relation to the major vessels.
