Abstract

INTRODUCTION AND OBJECTIVES: The diagnosis of cholesteatoma is based on clinical evaluation and computed tomography. New diffusion-weighted magnetic resonance imaging (MRI) techniques, without intravenous contrast, are capable of differentiating cholesteatoma from inflammatory tissue, cholesterol granuloma and granulation tissues. The technique is very helpful in differential diagnosis of cholesteatoma. Difficult cases can be detected and correctly diagnosed as well. The aim of this study was to evaluate sensitivity, specificity, positive predictive value and negative predictive value of the diffusion-weighted MRI in cholesteatoma diagnosis. METHODS: A prospective study was performed on 50 patients. Clinical and surgical findings were correlated with diffusion-weighted MRI results. RESULTS: Sensitivity, specificity and positive and negative predictive values were 100%, 14.29%, 87.76% and 100%, respectively. CONCLUSIONS: Diffusion-weighted imaging is an effective technique in cholesteatoma diagnosis.
