Abstract
Background: Brain neoplasms may be classified by the location of supratentorial, infratentorial and midline tumours. Of the supratentorial neoplasms, meningiomas are the most frequent extra-axial neoplasms. CT has become the most important diagnostic procedure in evaluating patients suspected of harboring an intracranial tumor. It is still considered the basic radiologic study since it gives specific information for the management of brain tumours and is minimally invasive. The purpose of this study was to assess the distribution, features, localization and extent of supratentorial neoplasms. Subjects and Methods: Fifty cases with symptoms of intracranial pathology and on CT found to have supratentorial tumours were studied. Results: The CT patterns of 50 supratentorial tumours were reviewed, out of which 30 cases i.e. 60%, were found to be intra- axial and 20 i.e. 40% extra-axial tumours. GBM formed the major group of the intra axial tumours i.e. 18 %, and meningiomas formed the major extra-axial tumours forming 26%. Conclusion: CT proves to be a valuable modality of imaging in evaluating the distribution, features, localizing and assessing the extent of various intra and extra-axial tumours in the supratentorial region.
Highlights
The concept of a tumor of the brain is, for most individuals and many physicians as well, one of the most dramatic forms of human illness
A brain tumor occurs the second most common form of malignancy in children and primary brain tumours rank from 6th to 8th in the frequency of all neoplasms in the adult
The present study objectives were to study the distribution of various supratentorial neoplasms, to study CT features of supratentorial neoplasms, and to localize and assess the extent of supratentorial neoplasms. [2]
Summary
The concept of a tumor of the brain is, for most individuals and many physicians as well, one of the most dramatic forms of human illness. Since the majority of these tumours present with nonspecific complaints such as headache, strokes like syndromes, or seizures, often a diagnosis is made or suggested initially by the findings on imaging studies Prognosis of these patients has improved considerably due to recent advances in diagnostic techniques, microsurgery and radiotherapy. CT has become the most important diagnostic procedure in evaluating patients suspected of harboring an intracranial tumor It is still considered the basic radiologic study since it gives specific information for the management of brain tumours and is minimally invasive. Conclusion: CT proves to be a valuable modality of imaging in evaluating the distribution, features, localizing and assessing the extent of various intra and extra-axial tumours in the supratentorial region
