RADIOLOGICAL EVALUATION OF PRIMARY BRAIN TUMOURS USING COMPUTED TOMOGRAPHY AND MAGNETIC RESONANCE IMAGING WITH HISTOPATHOLOGICAL CORRELATION

Abstract

BACKGROUND AND PURPOSE:
Brain tumours are among the common neoplasms of humans. Diagnosis of brain
tumours may be delayed as the initial symptoms and signs are vague and non specific.
Therefore clinicians rely mostly on imaging for an early and accurate diagnosis. Both
CT and MRI provide excellent anatomic details and information regarding the
presence, location and extent of brain tumours.
AIM AND OBJECTIVES:
To assess the role of CT& MRI in :
1. Detection & localization of primary brain tumours
2. Characterization of lesions
3. Giving specific diagnosis of the tumours using characteristics shown by CT and
MRI
MATERIALS AND METHODS:
● Study comprised of 23 patients with clinical suspicion of primary brain tumour
referred to the Department of Radiodiagnosis , ASRAMS , Eluru, Andrapradesh
, during a period of 8 months (January 2023 to August 2023 )
● The patients were subjected to CT brain using GE revolution ACT CT machine
(32 slice) and MRI BRAIN using SIEMENS 1.5 Tesla MRI
● Various radiological findings were observed and percentage of different
radiological findings were computed and compiled.
RESULTS :
In this study of 23 patients with primary brain tumours, 43% were gliomas (10 cases),
30% were meningiomas (7 cases), 30% were sellar and suprasellar lesions (7 cases),
8% schwannomas (5 cases) and 4% medulloblastoma (1 case) .
CONCLUSION:
CT and MRI are excellent modalities in diagnosis of primary brain tumours especially
in tumour location and extent. In majority of cases, it is possible to arrive at a specific
diagnosis based on CT & MRI characteristics .
