Abstract
It is difficult to diagnose the postoperative complications (especially recurrent tumor and infection) of patients who have undergone the surgery for the skull base tumor, because the lesion is located deep in the face and skull and the postoperative site is completely covered with the bone, soft tissue or transplanted materials. For this assessment, imaging modalities are most important.
In this article, 4 cases who had undergone the surgery for the skull base tumor and had complications of the recurrent tumor or infection were presented with long-term periodical assessment using several imaging modalities.
For detection of the recurrent tumor or other complications, gadolinium-DTPA (Gd)-enhanced MRI was most helpful. However, anatomical changes due to the surgery, transplanted material, postsurgical fibrosis make an accurate assessment of the recurrent tumor or other complications difficult. Therefore, periodical examinations using Gd-enhanced MRI is also important.
