Abstract
Aims and Objectives: 1. Diagnosis of intra cranial neoplasm on MRI. 2. To accurately determine the lesion characteristics.
Summary: In the present study for a period of 2 years (2015 – 2017) 130 cases from age group of 5-65 years suspected to be intracranial mass lesion on CT brain were elevated with MRI using various sequences and showed various supra and infratentorial and extra / intra axial cranial tumors.
Conclusion:
- Accuracy of predicting diagnosis of extra axial lesions is better than that of intra-axial lesion on MRI with 100% correlation with HPE in extra axial mass lesions
- Most of MR diagnosis correlated with histopathogical diagnosis.
- MRI is better in interpreting certain pathologies like infarction /reactive gliosis which produce similar morphological appearance to primary brain neoplasm on CT.
Keywords: MRI, intra axial; extra axial neoplasm, supratentorial, infratentorial tumors.
