Acute Mastoiditis Complicated with Concomitant Bezold’s Abscess and Lateral Sinus Thrombosis

Bezold's abscess is a very rare extracranial complication of acute mastoiditis. Lateral sinus thrombosis is another intracranial complication of acute mastoiditis that can occur, but there are only few reports of concomitant ispilateral Bezold's abscess and lateral sinus thrombosis with favorable outcome. We diagnosed and treated successfully a 14-year-old girl suffering from Streptococcus pneumoniae acute mastoiditis complicated with Bezold's abscess and lateral sinus thrombosis. Surgical treatment included myringotomy, cortical mastoidectomy, and Bezold's abscess incision and drainage. During the course of treatment, we concluded that lateral sinus thrombosis was not caused from mastoiditis by direct spread but from pressure on internal jugular vein caused from Bezold's abscess.
