Nasosinusal meningioma. A case report

Abstract

Introduction. Meningiomas are benign tumours of the arachnoid layer and although relatively frequent they have an intracranial development, implications of the visceral cranium or the neck are rare. Case presentation. We present the case of a 67-year-old male with an intracranial meningioma, with recurrences in the extra cranial area. We focused on clinical presentation, imaging studies and treatment options in this kind of tumour. Extra cranial meningiomas, primary or secondary, are rare and a sinonasal type should always be considered that it may be an extension of an intracranial tumour. The recurrence rate is moderate and outcome is good, but a missed follow-up may lead to unfavourable consequences. Treatment options may vary from „watch and wait“ to surgery – transcranial and endoscopic approaches, combined techniques – and even radiotherapy, depending on the site and extension. Conclusions. Endoscopic endonasal surgery may be a safe and effective way of treatment for skull base tumours, although it requires advanced techniques and a good knowledge of reconstruction of dura and skull base defects. There are also limitations, that can be surpassed with a combined approach.
