Background:

Isolated trigeminal neuropathy is uncommon; causes include trauma, inflammation, or neoplasm.

Methods:

We report a patient who fell and struck his head during a myocardial infarction, was treated with streptokinase, and developed symptoms and signs of an isolated trigeminal sensory neuropathy.

Results:

Imaging showed hemorrhage in the trigeminal nerve root; follow-up imaging showed resolution of the hemorrhage, but no underlying structural lesion.

Conclusion:

A combination of head trauma plus thrombolysis resulted in an isolated trigeminal neuropathy.

Résumé

RÉSUMÉ<span class='bold'><span class='italic'>Introduction:</span></span>

La neuropathie isolée du trijumeau est un problème rare causé entre autres par un traumatisme, de l’in- flammation ou une néoplasie.

<span class='italic'><span class='bold'>Méthodes:</span></span>

Nous rapportons le cas d’un patient qui s’est frappé la tête en tombant au moment d’un infarctus du myocarde traité par streptokinase et qui a développé des symptômes et des signes de neu- ropathie sensorielle isolée du trijumeau.

<span class='italic'><span class='bold'>Résultats:</span></span>

L’imagerie a montré une hémorragie dans la racine du nerf tri- jumeau. Au cours du suivi, l’imagerie a montré une résolution de l’hémorragie sans lésion structurale sous-jacente.

<span class='italic'><span class='bold'>Conclusion:</span></span>

Une malencontreuse coïncidence de traumatisme crânien et de thrombolyse a provoqué une neuropathie isolée du trijumeau chez ce patient.
