The common causes of
anosmia include sinonasal disorder, post-upper respiratory
infection,
trauma and
chemicals. Intracranial
tumor also frequently cause
anosmia, so it is not easy to
diagnose an intracranial
tumor in
patients who present with no definite related symptoms other than
anosmia. Therefore,
otolaryngologists should focus their
attention on these disorders when they see
patients with
anosmia. We have experienced a case of
olfactory groove menigioma presenting with only
anosmia. We herein
report this case with a brief
review of the
literature.
