Meningioma

A rare, mostly benign, primary tumor of the meninges (arachnoid cap cells), usually located in the supratentorial compartment, commonly appearing in the sixth and seventh decade of life, clinically silent in most cases or causing hyperostosis close to the tumor and resulting in focal bulging and localized pain in less than 10% of cases. Additional features may include headache, seizures, gradual personality changes (apathy and dementia), anosmia, impaired vision, exophthalmos, hearing loss, ataxia, dysmetria, hypotonia, nystagmus, and rarely spontaneous bleeding.

Anosmia

An inability to perceive odors. This is a general term describing inability to smell arising in any part of the process of smelling from absorption of odorants into the nasal mucous overlying the olfactory epithelium, diffusion to the cilia, binding to olfactory receptor sites, generation of action potentials in olfactory neurons, and perception of a smell.

Hemangiopericytoma in the Olfactory Groove: A Rare and Unusual Presentation.
Gupta R, Moore JM, Miller K, Harsh GR 4th.
Cureus. 2017;9(11):e1875.
Here we describe the rare presentation of a differentiated HPC masquerading as an olfactory groove meningioma in a 33-year-old female presenting with the progressive headaches, anosmia, and visual field disturbances.

We therefore describe a patient who presented with anosmia whose evaluation revealed a large olfactory groove meningioma.

Patients with olfactory, groove meningiomas may present with anostnia, Surgery in patients with intact olfaction can also lead to anosmia when the olfactory nerves are sacrified.

The existence of calcified, asymptomatic, trailing brain tumours, with an atypical and late evolution of unilateral olfactory meningioma, without Foster-Kennedy syndrome, demands from the beginning close surveillance and complex investigations, since a prolonged absence of anosmia and focal phenomena does not exclude the possibility of a meningioma of the olfactory groove, and may often lead to errors of diagnosis.
