Olfactory groove meningiomas can attain substantial size before producing enough symptoms alerting the patient or physician to the possibility of a tumor. The surgical goal is gross total resection in order to reduce the chances of recurrence, however, increased surgical complication rates can be seen with more aggressive resections. The optimal imaging follow-up time following gross total rese...

Objectives Meningioma recurrence remains a significant issue. No study has described the relationship between the clinical features and prognosis of communicating meningioma that primarily originates from the olfactory groove. The aim of the study was to identify prognostic factors of communicating olfactory groove meningiomas that could be stratified according to their risk of recurrence. Re...

AIM Olfactory groove meningiomas make up 4 to 13% of meningiomas. The first line treatment of meningiomas is surgery, but the extent and types of approaches advised for olfactory groove meningiomas are diverse, from aggressive skull base approaches to standard or minimally invasive craniotomies and endoscopic approaches. We retrospectively reviewed our series of olfactory groove meningiomas tha...

Olfactory groove meningiomas can present as large and insidious masses in the anterior cranial base. Due to their location and minimal clinical symptoms, these tumors can go undetected until they have grown extremely large. We present a clinical case and discuss the surgical management of a 63-year-old man who presented for an initial eye examination with bilateral visual loss for over 2 years ...

Intracranial schwannomas are benign tumors that arise from Schwann cells. Since it is well known that optic and olfactory nerves do not have a Schwann cell sheath, schwannoma should not develop from these nerves. We report a very unusual case of a 73-year-old female who presented with generalized seizures and had radiological features of an intracranial aneurysm. Additional imaging showed an ex...

BACKGROUND Olfactory groove meningiomas comprise 4-10% of the intracranial meningiomas. Generally they give signs of brain compression due to great size they reach before diagnosis. In this study, the clinical outcome of patients with olfactory groove meningiomas surgically treated was analyzed. METHOD 17 patients operated on from 1988-2006. Female: 16, Male: 1. Age: 19-76 years-old (mean=53....

OBJECTIVES Olfactory meningiomas are rare benign tumours and represent about 12% of all basal meningiomas. Anosmia is thought to be among the first symptoms, even though patients often present with headaches or visual problems. However, so far no detailed psychophysical tests of olfactory function have been performed in a large number of those patients. METHODS Twelve patients (five men, seve...

Introduction. Olfactory groove meningiomas cause progressive compression of the frontal lobes with posterior projection towards sella turcica. If large enough, these tumors may optic nerve and chiasm. The aim this study was to determine whether optical coherence tomography, as a method that objectively measures thickness retinal fiber layer ganglion cell complex thickness, provides realistic as...
