RT Journal Article SR Electronic T1 Diffusion-Weighted Imaging for Differentiating Recurrent Cholesteatoma from Granulation Tissue after Mastoidectomy: Case Report JF American Journal of Neuroradiology JO Am.

Mukherji YR 2002 UL http://www.ajnr.org/content/23/5/847.abstract AB Summary: Identification of recurrent cholesteatoma and differentiation from postoperative granulation tissue is important in a patient who has undergone mastoidectomy for cholesteatoma. We describe the diffusion-weighted imaging findings and apparent diffusion coefficient values in a case of recurrent cholesteatoma. This case suggests possible differentiation of cholesteatoma from granulation tissue on the basis of diffusion-weighted imaging findings.
