Facial myonecrosis following COVID-19

Abstract

Myositis and myonecrosis are rare sequela of coronavirus disease 2019 (COVID-19). Until now, it has not been seen in muscles of the head and neck. We present a 22-year-old male with 4 months of retroauricular headaches following COVID-19 infection. Magnetic resonance imaging revealed rim-enhancing fluid collections in the bilateral masticator spaces which were sampled by fine-needle aspiration. We also discuss this case in the context of the current understanding of COVID-19-related myositis.

Keywords: ADC, apparent diffusion coefficient; COVID-19; COVID-19, coronavirus disease 2019; CT, computed tomography; DWI, diffusion-weighted imaging; MRI, magnetic resonance imaging; Myonecrosis; Myositis.

(A) T2-weighted fat-suppressed and (B) contrast-enhanced T1-weighted DIXON fat-suppressed images show rim-enhancing fluid collections (arrows) involving the anterior aspect of the bilateral masticator spaces. (C) Diffusion-weighted and corresponding (D) apparent diffusion coefficient (ADC) map shows facilitated diffusion in the center of the fluid collections.
