Assessment of the postoperative course of excised brain abscess by computerized tomography.

We present two patients with brain abscess who underwent complete excision with a satisfactory clinical outcome although serial computerized tomography (CT) Scans in the early postoperative period seemed to indicate a large residual abscess in each case. We recommend treatment based on the clinical course rather than the CT scan appearance, indicate that earlier reports on this topic may be misleading, and suggest an explanation for these findings.
