Guillain–Barré syndrome with bilateral facial diplegia secondary to severe acute respiratory syndrome coronavirus-2 infection: a case report

Background The new coronavirus, known as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) owing to its similarity to the previous severe acute respiratory syndrome (SARS), is characterized by causing, in most patients, nonspecific symptoms similar to those of the common flu. It has been reported that many coronavirus disease 2019 (COVID-19) patients presented neurological symptoms that involve the central and peripheral nervous systems. In addition, there have been several reports of patients who presented Guillain–Barré syndrome related to COVID-19 , with sensory and motor compromise in the extremities. Case presentation In this report, we describe a rare case of Guillain–Barré syndrome in a 50-year-old Hispanic male with bilateral facial palsy as the only neurological manifestation, following SARS-CoV-2 infection. A complete neurophysiological study showed severe axonal neuropathy of the right and left facial nerves. Conclusion Regardless of severity, clinicians must to be aware of any neurological manifestation generated by COVID-19 and start performing more neurophysiological tests to determine if the infection induces an axonal, myelin, or mixed involvement of the peripheral nervous system.

Neurological manifestation of Vitamin D deficiency

Idiopathic intracranial hypertension, also known as pseudotumor cerebri, is a disorder with raised intracranial pressure, headache, papilledema, visual disturbances with a normal cerebrospinal fluid examination, and normal neuroimaging. It is rare in the pediatric population and may occur as a manifestation of underlying disorders. Vitamin D deficiency is a common deficiency in the pediatric age group. However, neurological manifestations are rare. Here, we present the case of a 5-year-old male child who presented with headache, vomiting, and hypertension; however, the neurological examination was normal but the neuroimaging was suggestive of pseudotumor cerebri. Appropriate investigations were done. The most likely cause of pseudotumor cerebri in this patient was the deficiency of Vitamin D. We have reported this case as pseudotumor cerebri is a rare neurological manifestation of Vitamin D deficiency.
