BACKGROUND
Supratentorial tumours mostly present with non-specific complaints such as
headache, stroke like syndrome or seizures. Often a diagnosis is made or
suggested initially by findings on imaging studies. We wanted to study the imaging
findings of supratentorial tumours, so as to deliver the best possible diagnosis and
treatment for the patient.
METHODS
All clinically suspected supratentorial brain tumour cases undergoing Magnetic
Resonance Imaging (MRI) at GSL Medical College and General Hospital,
Rajahmundry, were included in this study. All scans were performed with 1.5 Tesla
MRI. Pre-contrast scanning was done using axial T1, T2 and FLAIR; coronal T2
and sagittal T1 with a slice thickness of 5 mm. Post-contrast coronal, sagittal and
axial T1WI were obtained. If required, thinner sections were obtained in the region
of interest wherever necessary. Special MRI sequences like FLAIR (Fluid
Attenuated Inversion Recovery Sequence), and DWI (Diffusion Weighted Imaging)
were obtained.
RESULTS
In this study, 53 cases were diagnosed with supratentorial tumours. Glioma was
the most common diagnosis (49%). Peak incidence of neoplasms was seen in fifth
decade and the lowest incidence was seen in the first decade. 29 patients were
males and 24 patients were females. Headache was the commonest presenting
complaint. Twenty-three tumours were homogenous, 22 were heterogenous and
7 had non-enhancing pattern.
CONCLUSIONS
Multiplanar capability of MRI is helpful in identifying the precise anatomic location
and the exact extent of the tumours. Post contrast images clearly define the size,
margins, and nature of the tumour and also improves the differentiation between
the tumour and surrounding edema.
