Post viral cerebellar ataxia

Competing interests The authors declared that they have no competing interest. According to the literature, the diagnosis of varicella is based on clinical evidence of characteristic skin lesions in cerebeliti stages of development and resolution. Nil, Conflict of Interest: In our case series, AC was found out in 48 out of patients According to a report, it can occur with the rash or may be delayed for up to 2 weeks.

Controlled trial of acyclovir for chickenpox evaluating time of initiation and duration of therapy and viral resistance.

Methods We retrospectively reviewed the medical records of children admitted ceregelitis the hospital for varicella between 1 st October cerebeltis 1 st June and we compared our results with literature. Clinical presentation was similar in all cases except cases 1 and 2, who presented headache and behavioral changes in addition to their cerebellar symptoms. CSF electrophoresis was not done. This page was last edited on 29 Marchat Statistical Analyses Categorical data were given as number of cases and percentages, continuous variables were reported as median and range.


BE provided medical assistance to the patient and collected medical information, BM and CV revised the literature, LD supervised the neuroradiological examination included in the case report, TAE supervised the examination examination included in the case report, KA was involved in the clinical follow-up of the patient, VA supervised the patient treatment plan.

The hospitalization of our patients was longer than those reported in the literature 6. Routine laboratory findings were normal in all children. The results were limited to publications written in English, concerning the pediatric age 0—18 years and published during the period between June and June Cerebeliits authors reported that acyclovir is indicated because of disease severity, while others did not recommend it, based on the strength of evidence regarding autoimmune pathogenesis [ 22 – 252829 ].

Abstract Background Acute cerebellitis AC is the most common neurological complication of varicella. MRI changes with acute shingles. Eur J Paediatr Neurol. Table 2 Patients characteristics and outcome. Most pathologic studies have shown a picture more likely to be allergy-mediated injury.

If ataxia does not follow the expected time course or if suspect other causes then consider:. Grahn A, Studahl M. There was urinary retention. The pathogenic bases for these complications have been thought to be many. The burden of varicella complications before the introduction of routine varicella vaccination in Germany.

The radiculopathy symptoms were cured earlier but the cerebellar symptoms took 4 months to resolve fully.

At MRI, bilateral diffuse abnormalities of the cerebellar hemispheres are the most common imaging presentations but are not patognomonic and with a no evident prognostic value [ 27 ]. Finally, as well as in our case-series, other authors generally cerebelitus not refer invalidating problems at the follow-up [ 114 ].

Acute sickness due to cerebellar symptoms can mimic behavioural changes, but this was assessed only by the clinician not on a subjective parental account. These patients may benefit from a more aggressive therapeutic strategy and should have a closer follow-up.

Varicella zoster infection is known to cause neurological involvement. This can show that the virus has attacked the nervous system of the patient and resulted in the ataxia symptoms. Acute cerebellar ataxia in childhood: Clinical and pathologic correlates.

Drug treatment to improve muscle coordination has a low success rate. NCV study showed diminished C-map of lower limb peroneal nerves, suggestive of asymmetric axononeuropathy. The neurological examination showed normal higher functions, no signs of meningeal poat, normal cranial nerves and no evidences of cerebellar involvement.
