Streptococcus acidominimus infection in a child causing Gradenigo syndrome.
Gradenigo syndrome is a rare presentation of acute petrositis. The clinical triad of Gradenigo syndrome consists of acute suppurative otitis media, severe unilateral headache and abducens nerve palsy. We report the first case of Gradenigo syndrome caused by Streptococcus acidominimus, a Gram-positive coccus of the Streptococcus viridans group, which rarely causes deep-seated infection in humans.


CONCLUSIONS
Gradenigo syndrome may complicate acute otitis media and should be suspected in case of unilateral headache and abducens nerve palsy. Conservative medical treatment without surgery may be considered in some patients.
