Delayed Onset Bilateral Papilledema in a Young Boy's Eyes after Trauma.

Cerebral venous sinus thrombosis (CVST) is a rare venous thromboembolic disease that affects young adults in their thirties, with a female predilection. Head trauma accounts for only 1-3% of cases among possible etiologies. Here, we present a particular case of trauma-related CVST with delayed-onset symptoms and signs in a young boy. A 12-year-old boy presented to the emergency department with non-specific visual symptoms 11 days after head trauma. Apart from mild-grade disc swelling in the right eye and dyschromatopsia in both eyes, no significant findings were revealed during physical examinations and a non-contrast cranial computed tomography (CT) scan. Unfortunately, the patient suffered multiple seizure attacks the following day. Trauma-related CVST, complicated by delayed-onset increased intracranial pressure, and bilateral papilledema were finally diagnosed. Physicians need increased awareness of a possible CVST diagnosis if a patient with a history of head trauma shows persistent or worsening neurological symptoms despite negative results on serial non-contrast cranial CT scans.
