title: Radiological detection of glioblastoma recurrence.
abstract: Brain scanning is of great value in detecting glioblastomas. Since there is little stress upon the patient by this method it is specially suitable for follow-up after surgical treatment and radiation therapy of this tumour, thus giving the best chance of an early detection of a recurrence. On the other hand angiography is essential if further surgery is necessary. Diagnostic problems may arise when using arteriography in cases of avascular recurrences and lack of space-occupying symptoms due to the following factors: Position and small size of the recurrence, growth into the operation cavity, and postoperative cerebral atrophy. Avascular mass lesions of other origin may mimic a tumour recurrence in the angiogram. Thus, a combined use of isotope studies and radiological investigations is necessary for an unequivocal detection of glioblastoma recurrences.
