To raise awareness for diagnosis and management of Gradenigo's and Vernet's
First described in 1907, the classic triad of Gradenigo’s syndrome consists of suppurative otitis media, pain in the distribution of the trigeminal nerve and abducens nerve palsy, presumed secondary to extradural inflammation at the petrous apex of the temporal bone. Further spread of infection may give rise to other complications including meningitis, intracranial abscess, prevertebral/parapharyngeal abscess, spread to sympathetic plexus around carotid sheath, and spread to the skull base causing Vernet’s syndrome.
Case report

A 71-year-old Hispanic gentleman with poorly controlled diabetes, hypertension, hyperlipidemia, and chronic sinusitis, initially presented with acute onset horizontal binocular diplopia. Examination revealed right sixth and partial third nerve palsies. MRI did not reveal acute stroke. Additional workup of toxic, autoimmune, and infectious etiologies was unrevealing and he was discharged with a diagnosis of diabetic cranial neuropathy with recommendations to optimize neurovascular risk factors.  

He re-presented four weeks later with progressive dysphagia, dysarthria, right otalgia and hearing loss. ENT noted a peri-pharyngeal mass, followed by CT revealing subtle effacement of bilateral pharyngeal recesses with heterogenous mucosal enhancement, and bilateral mastoid and middle ear effusions. He was initiated on broad spectrum antibiotics for mastoiditis. MRI brain/orbits showed enhancement of the right orbital apex with suspected involvement of the superior and inferior orbital fissures. CT of the temporal bone confirmed right mastoiditis with concomitant osteomyelitis and a focal bony defect in the roof of the middle cranial fossa. Ear cultures and mastoid biopsy revealed C.parapsilosis. In addition to antifungal treatment, patient also required extensive supportive care but passed away several weeks later. <br bcx0"="">

  • Gradenigo’s and Vernet’s syndromes are uncommon clinical presentations of cranial neuropathies, but despite their rarity, remain highly clinically relevant entities. Elucidation of etiology determines management and prognosis, and thus, morbidity and mortality
