Clinical Practice and Cases in Emergency Medicine

Introduction: A Bezold abscess is a neck abscess characterized by inflammation and infection of the mastoid process that can invade deep into local anatomical musculature and vasculature.

Case Report: We highlight the case of a 62-year-old man who presented with ongoing left-sided neck pain, headache, and tinnitus that started two weeks prior to arriving at the emergency department. Physical examination showed tenderness to the left trapezius muscle, left-sided mastoid tenderness, and pearly tympanic membranes bilaterally. A computed tomography angiogram of the head and neck was performed due to concerns of vertebral dissection, which eventually led to a diagnosis of Bezold abscess.

Conclusion: Although Bezold abscess has been described in the medical literature, it is rarely encountered in modern clinical practice because the widespread use of antibiotic therapy prevents acute mastoiditis from progressing to abscess formation. We highlight the complexity of clinical presentation that can easily be mistaken for other medical conditions, such as occurred with our patient who presented with symptoms more consistent with vertebral dissection: neck pain; tinnitus; and headache, without associated ear pain or discharge.
