On examination, the left auricle is protruding and there is marked erythema, swelling, tenderness, and fluctuance overlying the left mastoid bone (Figure 23-1). Otoscopy reveals a purulent middle ear effusion. A computed tomography (CT) scan of the temporal bones reveals opacification of the mastoid air cells. A diagnosis of acute mastoiditis is made and the girl undergoes urgent myringotomy and tympanostomy tube placement and mastoidectomy. Postoperatively, she is treated with intravenous antibiotics and recovers completely.
