Introduction

DWI of Cholesteatoma

Benjamin Huang

Benjamin Huang

Cholesteatomas of the middle ear and mastoid are a major cause of morbidity among patients with chronic otitis media and eustachian tube dysfunction, due primarily to their destructive potential. While surgical resection successfully eradicates disease in the majority of patients, recurrences after … more »

The Utility of Diffusion-Weighted Imaging for Cholesteatoma Evaluation

John I. Lane

John I. Lane

We first became interested in utilizing non-EPI DWI for the detection of recurrent cholesteatomas after reading the published works of our European colleagues.1,2 Clinical diagnosis of recurrence is quite limited in patients following canal wall-up mastoidectomy and tympanoplasty procedures (often … more »

Diffusion-Weighted Imaging for Differentiating Recurrent Cholesteatoma from Granulation Tissue after Mastoidectomy: Case Report

Suresh Mukherji

Suresh Mukherji

Diffusion-weighted imaging  for distinguishing cholesteatoma from postoperative granulation is one of the most underutilized techniques for evaluating the temporal bone. Accurate detection of recurrent or residual cholesteatoma is difficult because the postoperative bony changes alter the classic CT findings necessary to confirm … more »

3T MR Imaging of Postoperative Recurrent Middle Ear Cholesteatomas: Value of Periodically Rotated Overlapping Parallel Lines with Enhanced Reconstruction Diffusion-Weighted MR Imaging

Pierre Lehmann

Pierre Lehmann

The importance of diffusion-weighted MR imaging in the detection of recurrent cholesteatoma was already known and quite well documented at the time of this study.

At the beginning, our 3T MRI was mostly used to explore brain. 3T allowed lowering section thickness without signal … more »
