[Radiological pictures of the skull following brain-tumor surgery]

In 90 patients, the majority of whom was operated upon for a brain tumour, we have systematically controlled the post-operative x-ray pictures of the skull. Clips set in during surgery, calcified epiphysis and changes of the sella due to pressure were the most important signs. To complete the follow-up of tumours we should like to propose to use clips not only as a hemostyptic measure, but also to have marks in cases of possible relapses.
