UNASSIGNED: We reported herein the case of a French young women presenting with ophtalmoplegia, cerebellar ataxia, and universal areflexia following a bariatric surgery (sleeve gastrectomy). A concomitant COVID-19 diagnosis was retained based on microbiological testing. The patient was successfully treated after high-dose intravenous thiamine, but areflexia persisted. Underlying COVID-19 related Miller-Fisher Syndrome was established on physical examination and confirmed by pathologic neurophysiological findings and elevated level of phosphorylated neurofilament heavy chain protein in cerebrospinal fluid analysis.
UNASSIGNED: Guillain-Barré Syndrome and its variants after SARS-CoV-2 infection are extremely rare. The measurement of phosphorylated neurofilament heavy chain protein should be considered as an easy tool to detect an early affection of the peripheral nervous system.
