Intracranial Tumours

Dosimetric Comparison of Two Craniospinal Radiotherapy Techniques for Treatment Optimization

Introduction: Orthogonal radial fields are those in which the central axes are perpendicular to each other. An example of these orthogonal fields is the set of craniospinal orthogonal fields that are used for radiotherapy of medulloblastoma. Craniospinal radial fields consist of two parallel-opposed fields for brain exposure and one or two posterior spinal fields for spinal cord exposure. The m...

Early Diagnosis of Intracranial Tumours *

CONSIDERABLE variation is to be found in the reported incidence of mental symptoms in cerebral tumours, dependent, in large measure, on the interpretation of the symptoms presented. That cerebral tumour is not a common cause of any of the recognized forms of mental disorder treated under certificate is apparent from the statistics of mental hospitals. Nevertheless, abnormal mental phenomena may...

Remote metastases from intracranial tumours.

A review of the primary tumours of the nervous system encountered over the past 16 years from the population of the west of Scotland uncovered only three tumours in which remote extracranial metastases had developed. In all three, there had been surgical intervention before the appearance of metastases. The findings in these patients are compared with those in other published accounts of this u...

Intracranial aneurysm formation after radiotherapy for medulloblastoma

BACKGROUND The development of an intracranial aneurysm after radiotherapy is rare but secondary effect of cranial irradiation in a primary disease treatment. CASE DESCRIPTION The patient was a 17-year-old male adolescent who was diagnosed as having a posterior fossa medulloblastoma when he was 8 years old. He had undergone tumor resection with radiotherapy and chemotherapy. A distal posterior...
