BACKGROUND
Brain tumours represents 1.7 % of all cancers and contributes 1.8 % of all cancer
deaths. Of all the brain tumours, 80 % are supratentorial.1 Magnetic resonance
imaging (MRI) is an important modality, having higher sensitivity for detecting
intracranial pathology. Multiplanar imaging is possible with MRI which helps in
detection, localization and characterization of the lesion. MRI examination has
helped in early diagnosis, accurate localization of the tumour, with prompt
initiation of appropriate medical or surgical therapy. Recent advances like
magnetic resonance (MR) spectroscopy, MR fluoroscopy with stereotactic guided
biopsy have revolutionized the role of MRI in study of intracranial tumours.
METHODS
A cross sectional study of 75 patients was done by Siemens Essenza 1.5T MRI
from June 2018 to June 2020 using dedicated head coil.
RESULTS
In our study, most of the patients were between 31 - 60 years of age (39 % of all
patients) with the largest group between 31 - 40 years (20 % of all patients). Out
of 75 cases of supratentorial neoplasms, 47 (72 %) were intra-axial lesions, 15
(23 %) were extra-axial lesions and 3 (5 %) were intra ventricular lesions. In this
study, 69 % of the lesions were solitary and 31 % were multiple. Most of patients
(89 %) showed some enhancement, most common being
heterogeneous/inhomogeneous enhancement. Commonest type of supratentorial
neoplasms were metastases comprising 29 % of this study.
CONCLUSIONS
Magnetic resonance imaging is an important modality, having higher sensitivity for
detecting intracranial pathology. Multiplanar imaging is possible with MRI which
helps in early detection, localization and characterization of the lesion. Metastasis
is the most common supratentorial tumour in this study followed by meningioma.
Intra-axial tumours are more common than extra-axial tumours in this study.
