Summary
This study presents the first evidence linking normalized cerebellar hypoperfusion on SPECT scans to positive clinical outcomes in adult cerebellitis patients. Cerebellar blood flow recovery can occur within three weeks, correlating with improved neurological function.
Area of Science:
- Neurology
- Neuroimaging
Background:
- Cerebellitis, an inflammation of the cerebellum, can lead to significant neurological deficits.
- The relationship between clinical recovery and neuroimaging findings, specifically Single Photon Emission Tomography (SPECT), in adult cerebellitis remains understudied.
Observation:
- A 63-year-old male presented with cerebellar dysfunction following a cough.
- Cerebrospinal fluid analysis revealed elevated protein levels; MRI scans were initially normal.
- SPECT imaging demonstrated unilateral cerebellar hypoperfusion, which normalized by the 20th day of illness.
Findings:
- The patient exhibited gradual improvement in gait and tandem gait stability over six months.
- This case provides the first evidence suggesting that normalization of cerebellar hypoperfusion detected by SPECT correlates with a favorable clinical outcome in adult cerebellitis.
Implications:
- Normalized cerebellar perfusion on SPECT scans may serve as an indicator of recovery in cerebellitis.
- Cerebellar hypoperfusion can resolve within three weeks, even in cases with persistent severe ataxia, highlighting the potential for neurological recovery.
