A 10-year-old boy sought care at an emergency department for severe right earache and headache. A computed tomography scan confirmed right mastoiditis and he underwent mastoidectomy. His headaches worsened and 2 weeks later he developed horizontal diplopia. His examination at the time of admission was normal except for bilateral papilledema with hemorrhages around the optic discs (Figure 1). He was uncooperative with visual field testing.
