Answer

CT scanning

  • A CT scan of the head may reveal a brain abscess. A CT scan of the surrounding soft tissue and osseous lesions is recommended in patients with malignant otitis externa to help define the intracranial and extracranial extent of disease.

  • Perform a CT scan of the abdomen as part of the workup for endocarditis, especially left-sided disease. Complications such as splenic abscesses require splenectomy before valvular replacement.

  • A CT scan of the chest is not usually indicated, except when respiratory failure requires better definition of chest involvement. With left-sided endocarditis, a CT scan of the chest also can reveal septic pulmonary emboli as a complication.

  • A CT scan of soft tissue and bone of skin infections may be required to exclude an abscess formation or osteomyelitis.
