Acute otitis media associated with Gradenigo syndrome and transverse sinus thrombosis: a case report

Gradenigo syndrome is associated with middle ear infection that extends to the petrous apex, leading to pain at the innervation site of the ophthalmic and maxillary branches of the trigeminal nerve and the development of abducens nerve palsy. Cerebral venous sinus thrombosis is a serious neurological complication of otitis media and occurs secondary to spread of the infection to the underlying bone. We herein report a pediatric case of otitis media associated with Gradenigo syndrome and ipsilateral sigmoid–transverse sinus thrombosis with magnetic resonance imaging findings.
