Summary

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.
