Abstract

Phantosmia is defined as the false perception of odors without any environmental odor stimulus. It is a very rare phenomenon, but it can be caused by a wide variety of conditions, such as viral or allergic rhinosinusitis, head trauma, brain tumor, migraine, temporal lobe epilepsy, stroke, and psychiatric conditions. If it is caused by a brain tumor such as glioblastoma, it can be controlled with steroids or antiepileptic drugs. Phantosmia can also be treated with surgical resection or adjuvant radiotherapy combined with chemotherapy. We report a case of glioblastoma presenting with phantosmia.
