Abstract. Cerebellar disorders due to herpes simplex virus (HSV) infection are rare and always associated with herpes simplex encephalitis. We report 2 cases . This article includes discussion of acute cerebellar ataxia (in children), acute cerebellitis, and acute postinfectious cerebellitis. The foregoing. Acute cerebellar ataxia is a syndrome that occurs in previously well children, often presenting Acute cerebellar ataxia, acute cerebellitis, and.

Autoantibodies in postinfectious acute cerebellar ataxia. Cerebellar images can be normal due the CT limitations on the evaluation of posterior fossa. Acute cerebellitis with near-fatal cerebellar swelling and benign outcome under conservative treatment with high dose steroids.

Open in a separate window. Changes to diet and nutritional supplements may also help. At admission, neurologic examination revealed normal cognition, ataxia, dysarthria with exacerbation of her dysphemia, dysmetria on the entire left side of the body, and nystagmus.

Acute cerebellitis in adults is a rare entity with a wide range in etiology, clinical presentation and outcome. Both patients had a history of renal failure, for which they received dialysis.

Therefore, it is advised to perform cranial imaging prior to lumbar ceerebellitis. In any case, since we demonstrated that children with pathological brain CT or MRI on admission had a higher probability of having long-term neurological sequelae, this sub-set of patients could csrebellitis the one to select for early and more aggressive treatment. A CT computed tomography scan with normal results can rule out the possibility of the presence of a posterior cerebdllitis tumor and an acute hemorrhage, which would both have abnormal results.


From this point a series of exclusion tests can determine if the current cerebbellitis of ataxia is a correct diagnosis or not.

Autoantibodies in childhood post varicella acute cerebellar ataxia. Selection criteria included acute onset of neurologic symptoms, signs of cerebellar dysfunction, absence of recent exanthem or exposure to such illnesses, and lack of familial skeletal or neurologic disease. Acute cerebellitis with tonsillar herniation: Neurological presentation was also often characterized by dysmetry and difficult speech.

Our study describes acute cerebellitis in adults.

It may show a homogeneous mass effect due the cerebellar swelling 1,4. This delay could explain the low number of pathological MRI cerebellitiis found in this series and therefore some cases of AC may have been missed because of this.

If you are walking, you might suddenly feel as if you are tipping over.

Reply to Wasko et al. Hayakawa H, Katoh T. PCR analysis of a second CSF sample obtained 14 days after the initiation of treatment was negative for HSV-1 DNA; an MRI performed 1 month after the onset of acute cerebellitis revealed complete disappearance of the bihemispheral enhancement of the cerebellar cortex figure 1C and 1D.

Post viral cerebellar ataxia – Wikipedia

Our patients experienced rapid clinical improvement and complete recovery after 2 weeks of treatment; HSV-1 DNA was undetectable in CSF samples obtained after 14 days of treatment, which is not surprising considering that HSV-1 DNA can disappear from CSF as early as 1 week after the beginning of specific antiviral therapy [ 36 ].


Electroencephalography revealed nothing abnormal, and a brain MRI revealed a partial bihemispheral cerebellar enhancement after gadolinium administration on T1-weighted images and an increased signal intensity with a mild cerebellar swelling on fluid-attenuated inversion recovery images figure 2A and 2B. The most common presenting sign was ataxic gait; however, truncal ataxia, action tremor, and dysmetria were also frequently seen. A cerebwllitis microbiological diagnosis was obtained in 2 cases by positive PCR on cerebrospinal fluid VZV and parainfluenzae virus.

Certainly, 1 of the confusions is whether acute cerebellar ataxia, in which there is typically no alteration in consciousness, and crrebellitis cerebellitis, which is often associated with encephalopathy, are in fact 2 separate conditions.

Weiss and Carter reexamined 18 of 23 patients previously reported in the literature to provide information on the course and prognosis of acute cerebellar ataxia in children Weiss and Carter In each case, the following data were collected: The treatment depends on the widely diverse etiology, and treatment with steroids is recommended in the case of cerebellar oedema and hydrocephalus.

Central nervous system infections caused by varicella-zoster virus. Unlike some prior and subsequent studies, they excluded patients with altered mental status or seizures, arguing that the original description by Batten in was of children with acute ataxia and normal mentation.
