Background: Meningioma is the second most common type of brain tumors. Many meningiomas discovered incidentally via Magnetic Resonance Imaging (MRI) for conditions such as head trauma or sinus problem. 
Aim: To throw a light on the relation of MRI findings with histopathology of meningioma. 
Methods: A total of 25 patients with meningioma were included in the study. They were surgically treated in Dept. of Neurosurgery, hospital of specialized surgery, Medical complex. Radiological examination for all patients was carried out in the Institute of Radiology or hospital for specialized surgery. Review of records was done. Chi square and F test were carried out to examine the association of variables. 
Results: Meningiomas were predominant in females (64%). The median age was 50 years. The types of meningioma were meningothelial (48%), fibrous (20%), angiomatous (16%) transitional type (12%) and atypical (4%). There was no significant association between histopathology with MRI findings on T₁ (p=0.04). The association between histopathology with findings of T₂ was significant (p=0.006). Edema was observed in 80% of cases. Heterogeneity of contrast enhancement was found in 20% of meningioma. 
Conclusion: The signal intensity of meningiomas on T₂- weighted images correlates with, and can serve as a crude predictor of histopathologic type. Tumors significantly hypointense to cortex tend to be composed primarily of fibrous or transitional elements.
