Background:

Posterior rupture of a sphenoid sinus mucocele is a rare cause of brainstem injury.

Methods:

Case report.

Results:

A healthy young woman with a history of prior surgical excision of nasal polyps presented with a headache and evolving neurologic symptoms. The clinical presentation and imaging studies were consistent with a posterior rupture of a large sphenoid mucocele with subsequent inflammatory changes in the brainstem and evidence of brainstem stroke. Relatively rapid recovery coincided temporally with the resolution of local inflammation. Longer-term recovery continued over months, as expected following stroke.

Conclusions:

Posterior rupture of a sphenoid sinus mucocele may cause brainstem injury by multiple mechanisms.

Résumé:

La rupture postérieure d’un mucocèle du sinus sphénoi’dal est une cause rare de lésion du tronc cérébral.

Il s’agit d’une observation. Résultats : Une jeune femme en bonne santé, qui avait subi antérieurement une excision chirurgicale de polypes nasaux, a consulté pour une céphalée et des symptömes neurologiques progressifs. Le tableau clinique et l’imagerie étaient compatibles avec une rupture postérieure d’un gros mucocèle sphénoidal ayant provoqué de l’inflammation et des signes d’accident vasculaire érébral au niveau du tronc cérébral. La écupération s’est poursuivie pendant plusieurs mois, comme on peut s’y attendre après un accident vasculaire cérébral

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

La rupture postérieure d’un mucocèle du sinus sphénoidal peut causer une lésion du tronc cérébral par plusieurs mécanismes.
