Abstract

The diagnosis of cholesteatoma is mainly established by clinical signs,and can be improved by radiological imaging. Recently, the use of magnetic resonance imaging (MRI) with HASTE sequence has emerged as a sensitive and specific diagnostic tool for cholesteatoma, which allows differentiating it from inflammatory-fibrotic tissue present in patients who have undergone previous surgery ear. Here, we present four cases of patients with a history of ear surgery and a suspected cholesteatoma in the same ear, performing HASTE MRI and subsequent surgery, presenting a high correlation between MRI and surgical outcome. More patients are needed to determine the sensitivity and specificity in the diagnosis of cholesteatoma inpatients with previous ear surgery.
