ABSTRACT
Motor chronic inflammatory demyelinating polyneuropathy (M-CIDP) is a form of atypical CIDP. This article presents a clinical observation of M-CIDP in a 15-year-old boy, as well as a description of laboratory and instrumental diagnostic data. The boy had a chronic development (> 2 months) of flaccid tetraparesis, predominantly of the proximal muscles of the limbs, without sensory disorders. According to electroneuromyography, there were signs of demyelinating lesions of the proximal parts of the peripheral nerves. There was an increase in the thickness of the nerves of the upper limbs according to ultrasound. In the liquor protein-cell dissociation, as well as in the blood, IgG antibodies to the surface glycoprotein S of the SARS-CoV-2 coronavirus were found. The clinical and neurophysiological picture corresponded to the reliable criteria for CIDP. The therapy with intravenous immunoglobulins had a significant positive effect in the form of an increase in the strength of the limb muscles.Copyright © Russian Neurological Journal.

ABSTRACT
We have presented the first description of acute bilateral neuropathy of the abducens nerve associated with COVID-19 in a child. A boy aged 2 years 2 months acutely developed bilateral convergent strabismus, the next day fatigue, drowsiness, and a single vomiting not associated with food intake, were joined. A differential diagnosis was performed between brainstem encephalitis, other organic (non-inflammatory) lesions of the brain stem, and idiopathic bilateral neuropathy of the abducens nerves. According to laboratory data, mild lymphocytosis, mild eosinophilia were detected, according to polymerase chain reaction DNA of the herpes virus type 1/2, cytomegalovirus, herpes virus type 6, Epstein-Barr, tick-borne encephalitis, borrelia, anaplasma, RNA ehrlichia were not detected. IgM and IgG to tick-borne encephalitis were not detected. Neurophysiological and neuroimaging examinations did not reveal any pathology. On the 6th day of the disease, SARS-CoV-2 RNA was detected by polymerase chain reaction of the nasopharynx and oropharynx discharge. The final diagnosis was formulated - bilateral neuropathy of the abducens nerves. Bilateral convergent paralytic strabismus. Concomitant diagnosis: new coronavirus infection, subclinical form (positive by polymerase chain reaction in the discharge from the throat and nose of the 2019-nCoV coronavirus (SARS-CoV-2) RNA). Decrease in the severity of strabismus was noted over time against the background of the therapy. Clinicians dealing with the COVID-19 should also pay attention to its ophthalmological manifestations and take into account that it can debut with them, as was in our case.
