Odontogenic Lemierre’s syndrome with septic superior ophthalmic vein and cavernous sinus thrombophlebitis complicated by blindness and ophthalmoplegia

ABSTRACT

Lemierre’s syndrome is a triad consisting of oropharyngeal infection, internal jugular vein thrombophlebitis, and systemic embolisation typically involving lung and brain. Orbital involvement in this life-threatening condition is rare but potentially blinding and may be an indicator of intracranial involvement. We describe a case of odontogenic Lemierre’s syndrome complicated by extensive orbital and intracranial septic venous thrombosis, with optic and cranial neuropathy resulting in monocular blindness and ophthalmoplegia. A multidisciplinary approach with abscess drainage, antibiotic and antithrombotic therapy, and close radiological monitoring was critical for preserving contralateral vision and neurological function.
