Insights into Gradenigo syndrome: Case presentation and review

Abstract

Gradenigo syndrome (GS) is characterized by a triad of clinical features: abducens nerve palsy, retro-orbital pain, and otorrhea, arising as a complication of suppurative otitis media. Herein, we present a case of GS in a 15-year-old male patient, secondary to left otitis media. The patient exhibited fever, otorrhea, accompanied by diplopia, retrobulbar pain, and headache. Imaging studies demonstrated petrous bone destruction and inflammatory changes with opacification of petrous bone, mastoid cells and surrounding structures, confirming the diagnosis of GS. Treatment included intravenous antibiotics and anticoagulants, resulting in the resolution of symptoms and radiological improvement. GS, though rare, warrants prompt recognition and appropriate management to prevent severe complications. Diagnostic imaging plays a crucial role in evaluation, and treatment often involves prolonged antibiotic therapy and, in severe cases, surgical intervention. Understanding the clinical presentation and management strategies is essential for clinicians encountering this condition.
