Patients with coronavirus disease 2019 (COVID-19) may have symptoms of anosmia or partial loss of the sense of smell, often accompanied by changes in taste. We report 5 cases (3 with anosmia) of adult patients with COVID-19 in whom injury to the olfactory bulbs was interpreted as microbleeding or abnormal enhancement on MR imaging. The patients had persistent headache ( = 4) or motor deficits ( = 1). This olfactory bulb injury may be the mechanism by which the Severe Acute Respiratory Syndrome coronavirus 2 causes olfactory dysfunction.
新型冠状病毒病 2019(COVID-19)患者可能有嗅觉丧失或部分嗅觉丧失的症状,常伴有味觉改变。我们报告了 5 例(3 例有嗅觉丧失)COVID-19 成年患者,其嗅球损伤被解释为磁共振成像上的微出血或异常增强。患者持续头痛(=4)或运动功能障碍(=1)。这种嗅球损伤可能是严重急性呼吸综合征冠状病毒 2 导致嗅觉功能障碍的机制。
