Ataxia refers to motor incoordination that is usually most prominent during movement or when a child is attempting to maintain a sitting posture. The first part of the review focuses on the anatomic localization of ataxia — both within the nervous system and without — using a combination of historical features and physical findings. The remainder of the review discusses etiological considerations that vary depending on the age group under consideration.
Tuberculous infection of neuroparenchyma is commonly manifested on magnetic resonance imaging as meningitis with basal exudates and associated complications. Involvement of supratentorial neuroparenchyma is far more common than infratentorial compartment. Variation in imaging finding of infratentorial tuberculous involvement is challenging for a radiologist.
Volume 5, Number 5, Maypages It is almost always seen before 6 years of age and very few adult cases are reported in literature. We present a year-old patient with post-EBV cerebellitis who presented with ataxia and slurred speech 2 weeks after infectious mononucleosis.
Cerebellitis associated with herpes zoster has rarely been observed. We report here a year-old man who had a history of anterior resection for sigmoid colon cancer and presented during chemotherapy with vesicular rash of the left ear, neuralgic pain in the postauricular area, and ataxic gait. After a while, he developed left peripheral facial palsy, fever, aggravated gait ataxia, and prolonged nausea and vomiting.

Orlando G. Cerebellar ataxia is a common finding in neurological practice and has a wide variety of causes, ranging from the chronic and slowly-progressive cerebellar degenerations to the acute cerebellar lesions due to infarction, edema and hemorrhage, configuring a true neurological emergency. Acute cerebellar ataxia is a syndrome that occurs in less than 72 hours, in previously healthy subjects.
This has resulted in the use of other imaging modalities, such as single-photon emission computed tomography, to aid diagnosis. As cerebellar ataxia progressed in parallel with cerebral spinal fluid pleocytosis, MRI findings indicative of cerebellar inflammation resolved, while single-photon emission computed tomography showed cerebellar hyperperfusion. Recovery of neurologic function was accompanied by clearing of the pleocytosis and residual MRI-detected cerebellar atrophy.
All data generated or analyzed during this study are included in this published article and its Additional information files. Acute cerebellitis is a rare disease with the majority of cases described in children. Little is known about the clinical characteristics and outcome in adults.
Cerebellar disorders due to herpes simplex virus HSV infection are rare and always associated with herpes simplex encephalitis. We report 2 cases of severe primary acute cerebellitis caused by HSV type 1 that were identified by nested polymerase chain reaction performed on cerebrospinal fluid samples. Herpes simplex virus type 1 HSV-1 is one of the most common causes of sporadic viral encephalitis in adults.
Assess for presence or absence of associated neurologic abnormalities which suggest life threatening or treatable conditions. If there is a clear history of Acute Cerebellar Ataxia with preceding viral prodrome, then no investigations may be necessary, however close follow up will be required. If ataxia does not follow the expected time course or if suspect other causes then consider :.
