Abstract
It is unclear whether a linear contrast enhancement at the edges of the operative site on early CT scan indicates a residual tumor or rather reflects postoperative changes. We have studied 15 patients treated with surgical removal of malignant brain tumor, submitted to periodic CT scan. The enhancement of linear contrast was due to a residual tumor, when seen on very early CT scan (within 24 hours after surgery). If occurring later, this enhancement was either generated by a residual tumor or by post-operative changes.
