Abstract
INTRODUCTION
Pleural fluid effusion is a possible harmful effect of sodium valproate. It most often consists in polynuclear eosinophilic pleurisy and occurs within months of treatment initiation.
CASE REPORT
We report on a case of sodium valproate-induced pleural effusion occurring more than 12years after initiation of treatment. The original formula was variegated and not eosinophilic. The patient exhibited contralateral recurrence with continued treatment. Once treatment was discontinued, there was no recurrence during three-year follow-up.
CONCLUSION
Sodium valproate-induced pleural effusion can present an atypical polymorphous picture leading to erroneous diagnoses.
