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.
