Transient cerebellar dysfunction after head injury can occur, presenting as temporary ataxia and speech difficulties. Imaging reveals cerebellar lesions, suggesting trauma and ischemia as the cause.

Area of Science:

  • Neurology
  • Neurotraumatology
  • Neuroimaging

Background:

  • Head injuries can lead to various neurological deficits.
  • Transient cerebellar dysfunction is an uncommon sequela of head trauma.

Observation:

  • Three patients presented with acute cerebellar signs including ataxia, nystagmus, and dysarthria immediately post-head injury.
  • These symptoms resolved gradually in all patients.

Findings:

  • Standard cerebrospinal fluid and computed tomography (CT) scans were unremarkable.
  • Magnetic resonance imaging (MRI) and single-photon emission computed tomography (SPECT) identified cerebellar lesions.
  • These findings differentiate cerebellar concussion from contusion.

Implications:

  • The study suggests a potential pathophysiological basis involving the synergistic effect of trauma and ischemia.
  • This understanding may aid in diagnosing and managing similar cases of transient cerebellar dysfunction.
