Acute hemicerebellitis in a young adult: a potential pitfall
Hemicerebelite aguda em adulto jovem: uma armadilha em potencialA 20-year-old man presented with a new headache for 21 days. His neurological examination showed mild right-side ataxia while walking in tandem. Brain MRI revealed extensive hyperintensities in the right cerebellar hemisphere in FLAIR/T2WI and moderate choline peak and low NAA ([Figure 1]). The viral and rheumatological panels in serum were negative. After 8 months, there was lesion regression ([Figure 2]). Combined lesion evolution and spectroscopy findings, inflammatory nature was suggested.

The diagnosis of hemicerebellitis is uncommon in adults but more common in children[1]. Spectroscopy could help differentiate from mimicking neoplastic lesions (e.g., Lhermitte-Duclos syndrome)[2] and avoid unnecessary interventions.
