ROLE OF MRI IN EVALUATION OF INTRACRANIALAS WELLAS SPINAL
EPIDERMOIDS AND ITS CORRELATION WITH POST OPERATIVE
HISTOPATHOLOGY.

Background: - Epidermoid tumors are benign slow-growing tumors that usually manifest as insinuating masses. MRI evaluation is most sensitive radiological modality available in evaluation & characterization of intracranial epidermoid tumors. It can be accurately differentiated from arachnoid cyst from various characteristic features on MRI. However, post operative histopathology is the gold standard for diagnosis as well as confirmation of MRI findings. Conclusion: - Epidermoid tumors can be accurately diagnosed with MR imaging with our study showing around 91% sensitivity and 75% specificity, positive predictive value 95% and negative predictive value 60%.
