Overview
Physical Examination
The diagnosis of mastoiditis is clinical—based on the medical history and physical examination. Imaging studies may provide additional information; the study of choice is the CT scan, which may show focal destruction of the bone or signs of an abscess (a pocket of infection). X-rays are not as useful. If there is drainage, it is often sent for culture, although this will often be negative if the patient has begun taking antibiotics.
