Abstract
With an increasing number of cases of Coronavirus disease 2019 (COVID-19), various neurological complications have been reported; however, some of these have not been fully elucidated. We herein report on 2 cases in which lesions at the bilateral globus pallidus and substantia nigra were observed. The patients were a 27-year-old male and a 61-year-old female. They underwent ventilation management due to COVID-19 pneumonia with hypoxemia. However, even after the sedative had weakened, the state of consciousness disturbance was found to have continued. Brain magnetic resonance imaging was performed for both patients. From the bilateral globus pallidus to the substantia nigra of both, the fluid attenuated inversion recovery images and T2-weighted images indicated high intensity, while the diffusion-weighted image resulted in high intensity and low apparent diffusion coefficient. Regarding the 61-year-old female patient, head computed tomography also indicated low density at the bilateral globus pallidus. The patients did not show any improvement in their neurological findings while hospitalized. Although COVID-19 associated with bilateral globus pallidus and substantia nigra lesions are rare, the neurological prognosis may be poor. We believe that attention should be paid to these imaging findings at the onset of consciousness disturbance.
