Eagle’s Syndrome with Papilledema: A Case Report

Purpose: We present a case of Eagle’s syndrome secondary to styloid process enlargement in a patient with papilledema.Case Summary: A 46-year-old male presented with a 10-day history of bilateral blurred vision. Despite a best-corrected visual acuity of 20/20 in both eyes, fundoscopic examination revealed bilateral optic disc swelling. Brain magnetic resonance venography (MRV) demonstrated tortuous and narrowed bilateral internal jugular veins. Neck computed tomography venography (CTV) confirmed bilateral internal jugular vein stenosis secondary to enlargement of styloid and transverse processes of the first cervical vertebra, consistent with Eagle's syndrome. Treatment with oral acetazolamide led to improvement in papilledema and visual symptoms.Conclusions: Styloid process enlargement can lead to compression of adjacent structures, including blood vessels and nerves. In our patient, compression of the internal jugular vein contributed to papilledema. The presence of papilledema and internal jugular vein stenosis on brain MRV should raise suspicion for Eagle's syndrome. Neck CTV is crucial for evaluating the anatomical relationship between vascular structures and bony elements, aiding diagnosis and guiding treatment.
