OBJECTIVE: Spontaneous dissection of the vertebral artery is a dangerous and often underdiagnosed cause of posterior circulation and occipital lobe @entity64 in the young. @entity4066 should be considered in young @entity1 with a history of minor, nontraumatic changes in head position and @entity227 . METHODS: Clinical records for this @entity1 were retrospectively reviewed at Miami @entity1 's Hospital and associated pediatric ophthalmology clinic. RESULTS: A previously healthy 8-year-old @entity1 presented to the emergency department with a 2-day history of @entity10 and @entity227 that developed after going on a high-velocity amusement park ride. Confrontation visual field testing showed a @entity227 superiorly. Computer topography scan of the head without contrast was performed and showed bilateral @entity75 consistent with @entity1188 . A filling defect was seen in the transverse portion of the right vertebral artery at the level of C2 as it exited the right transverse foramen, consistent with an acute arterial dissection at this level. Automated visual field testing showed macular sparing left homonymous superior @entity1805 . CONCLUSIONS: Most @entity1 with @entity4066 present with signs of posterior circulation @entity63 consisting of @entity51 , @entity4048 . This case report highlights the unique clinical features and diagnostic imaging seen in the work-up of this rare disease process and exemplifies the importance of identifying acute visual symptoms in an emergency situation.
