A 56-year-old woman with a history of hypertension was diagnosed with coronavirus disease 2019 (COVID-19). On the fourth illness day, her condition became severe, and she was admitted to the intensive care unit and treated with high-flow oxygen via a mask. She recovered and was discharged on Day 11 of hospi-talization (the 14th day of COVID-19). One week after discharge (3 weeks after onset), she noticed pain in the muscles of her right limbs. The pain in her right limbs persisted and 12 months after COVID-19 onset, she consulted her primary care doctor and was referred to us because of suspected long COVID. On neurological examination, although spontaneous pain was noted, no grasping pain or paresthesia was observed. Apart from the pain in her right arm, no abnormal neurological findings were detected. Brain magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA) were performed. Susceptibility-weighted MRI revealed a linear hypo-intensity inside the postcentral gyrus, surrounded by atrophy (Figure 1a, red arrow). No abnormal findings were observed on MRA (Figure 1b).
