“…[1][2][3][4][5][6][7][8][9] In all these 9 cases, as in our patient, the clinical symptomatology was characterized by progressive signs of intracranial hypertension, such as headache, vomiting, and neck stiffness, and none of them had cerebellar signs, namely, ataxia or dysarthria.…”

Acute Pseudotumoral Hemicerebellitis in a Child

et al. 2014

A pseudotumoral presentation of acute hemicerebellitis is rare in pediatric age. The authors report a new single case study of a 7-year-old child with pseudotumoral unilateral cerebellitis mimicking an intracranial tumor, which clinically presented itself with signs of intracranial hypertension and mild contralateral hemiparesis, completely recovered after anti-inflammatory therapy. Brain magnetic resonance imaging (MRI) was essential for the differential diagnosis between inflammatory and neoplastic processes. The literature highlighting specific clues about pseudotumoral hemicerebellitis as a distinct clinical and radiological entity is reviewed.

“…Classic imaging features include expansive T2 prolongation within the cerebellar white matter with or without enhancement. 13,16 Pial enhancement along the cerebellar folium is often observed. Interval improvement of imaging findings and the absence of a well-defined mass are characteristic.…”

“…13 Most cases of cerebellitis are self-limited and respond to steroid, antibiotic, or antiviral therapy without significant morbidity. 16 Hemicerebellitis is a rare unilateral presentation of cerebellitis, whereas pseudotumoral hemicerebellitis is an exceptionally unusual manifestation of hemicerebellitis in which a unilateral cerebellar inflammatory infiltrate mimics a tumor. It may present with significant mass effect causing brainstem compression, tonsillar herniation, or acute hydrocephalus requiring surgical intervention.…”

Acute cerebellitis is an inflammatory process that usually affects bilateral cerebellar hemispheres in the pediatric population. Pseudotumoral hemicerebellitis is an extremely rare presentation in which unilateral cerebellar involvement mimics a tumor that can exert significant mass effect on the surrounding structures, which may require surgical intervention. Magnetic resonance imaging characteristics that suggest cerebellitis include cerebellar swelling, T2 hyperintensity, and pial enhancement. Advanced neuroimaging, including MR perfusion and MR spectroscopy, may be helpful in excluding other diagnoses. The authors present the case of pseudotumoral hemicerebellitis in the oldest documented patient, a 73-year-old man who required surgical decompression, and they provide a brief discussion of advanced neuroimaging findings.

Acute Cerebellitis in Children: A Variable Clinical Entity

et al. 2018

View full text Add to dashboard Cite

Acute cerebellar ataxia is the most common cause of acute ataxia in children and it usually runs a self-limiting and ultimately benign clinical course. A small proportion of children have evidence of inflammatory swelling in the cerebellum. Many of these children suffer more severe and potentially life-threatening forms of cerebellar ataxia and may need more intensive treatments including urgent neurosurgical treatments. This more severe form of acute cerebellar ataxia is often termed acute cerebellitis. Many children with acute cerebellitis have long-term neurological sequela and evidence of structural cerebellar changes on follow-up imaging. Several patterns of cerebellar inflammation have been described. The authors describe the variabilities in the clinical and radiological patterns of disease in the cases that have been described in the literature.
