Abstract
PURPOSE
Pseudotumoral hemicerebellitis is an acute, unilateral inflammation of the cerebellum that typically affects the pediatric population. The purpose of this paper is to review cases of pseudotumoral hemicerebellitis in the literature and evaluate if treatment with systemic corticosteroids reduces length of time to symptomatic recovery.
METHODS
We present a case report of a 12-year-old male with pseudotumoral hemicerebellitis and unilateral cerebellar dysfunction. Additionally, we review the thirty-five reported cases of pseudotumoral hemicerebellitis with respect to length of time to symptomatic recovery with or without systemic corticosteroid treatment.
RESULTS
Thirty cases reported length of time to symptomatic recovery. Including our case, the mean time to recovery for those treated with systemic corticosteroids (n = 20) was 48.05 days (SE = 16.3). The mean time to recovery for those treated without (n = 10) was 86.7 days (SE = 29.3).
CONCLUSIONS
Treatment with systemic corticosteroids was associated with a faster time to symptomatic recovery compared to without. Regardless of etiology, reducing inflammation and mass effect involved in pseudotumoral hemicerebellitis may be integral to a more rapid return to neurological baseline.
