FERRARI, Luciana A. et al. Olfactory bulb abnormalities identified using magnetic resonance in a cohort of patients with anosmia after COVID-19. Rev. argent. radiol. [online]. 2024, vol.88, n.2, pp.66-70. ISSN 1852-9992.  http://dx.doi.org/10.24875/rar.22000087.

Anosmia, a frequent symptom among patients affected by COVID-19 and often associated with alterations in taste, does not have a clear pathophysiological basis in this context. Magnetic resonance imaging enables the structural assessment of the olfactory nerve, olfactory bulb, and primary and secondary cortices. In this group of patients with post-COVID anosmia, were identified structural abnormalities at the level of the olfactory bulb mainly depicted as elevation of the signal in T2-weighted sequences, and to a lesser extent as an increase in their volume. These characteristics were interpreted in probable relation to edema and inflammation after the viral infection, showing in certain cases asymmetry of the olfactory bulbs.
