title: Computed tomography in the postoperative patient.
abstract: Nine cases of patients in whom intracranial infection was suspected after operation are presented. Lesions with ring enhancement were seen in all of these patients. The differentiation of enhancement, seen as a normal postoperative phenomenon, from residual neoplasia and cerebral abscess can be difficult. This can be resolved by serial and sequential-delayed CT, and thus unnecessary re-exploration may be prevented.
