ABSTRACT

Olfatory groove meningiomas are the 8% of the all intracranial meningiomas. The principal symptoms and signs are altered in height cerebral functions, affection to cranial nerves (anosmia, optic atrophy, and papiledema). The diagnosis by X-rays, computed tomography (CT), magnetic resonace imaging (MRI) and some one cerebral angiography and preoperative embolization. The treatment of election is surgical and this tumors may have recurrence. Objective: to present the surgical results of 5 patients with olfatory groove meningiomas. Method and clinical material: retrospective review of 5 patients with olfactory groove meningiomas, in the period of december 2003 to february 2005, with treatment in the Department of Neurosurgery in the Hospital Central Sur de Alta Especialidad. Results: fifth patients with olfatory groove meningiomas. The principal clinical manifestations were headache, seizures, altered height cerebral functions and physical signs, affection to cranial nerves I and II. The diagnosis by imaging by X-rays, CT, MRI in the 5 cases and cerebral angiography in three and of this, in two preoperative embolization. In the 5 patients we make surgical resection Simpson’s grade I, by supraorbital bilateral approach way subfrontal; in two patients surgical reintervention, one by hematoma in the surgical field and the other by leakage of the frontal sinus to surgical field, in the two cases we resolved their complications. One patient had recurrence. Conclusion: olfactory groove meningiomas are presented with frequency relative; the diagnosis is by X-rays, CT, MRI and they are a challenge to surgeon in the resection and to avoid complications.
