Introduction
SARS-CoV-2 infection and COVID-19 disease have been linked to a variety
of olfactory disorders, especially anosmia, phantosmia, and dysgeusia
(1-4). Phantosmia is a subjective olfactory disorder defined as a
perception of odor without an actual activating odor. In the literature,
olfactory hallucinations were linked to migraine headaches, endoscopic
skull base surgery, intracranial tumors, brain radiation treatment, and
head injuries (5). The smell is generally only noticeable for a few
minutes the first time it is experienced, and it almost always appears
out of nowhere (6). Among the first signs of COVID-19 disease is
olfactory impairment, which can manifest as hyposmia, anosmia, or a
sudden loss of smell (7). However, there has never been a report of
COVID-19-related phantosmia or olfactory hallucination in Bangladesh.
COVID-19 patients who had olfactory hallucinations are reported in this
paper.
