Seizure and altered mental status in a 12-year-old child with Shigella sonnei gastroenteritis.

We report a case of Shigella-associated altered mental status and seizure in a 12-year-old boy. Although seizure is a known complication of shigellosis, it is quite unusual in patients older than 9 years. This case illustrates the importance of considering the diagnosis of shigellosis in any pediatric patient with altered mental status or seizure in the context of gastrointestinal symptoms such as diarrhea.
