Learning objectives
Middle ear cholesteatoma is a common inflammatory disease that requires surgery due to potentially serious intracranial complications.
Diagnosis of cholesteatoma is mainly clinical,
with computed tomography (CT) used to evaluate disease extension before surgery.
Certain patterns of bone erosion are specific,
but CT attenuation does not allow differentiation from other inflammatory middle ear diseases.
With its high tissue discrimination and contrast resolution,
magnetic resonance imaging is valuable in diagnosis of cholesteatomas.
The learning objectives of this educational exhibit are:
- To review the role of HRCT and MRI in the diagnosis of middle ear cholesteatoma before and after surgery.
- To report the advantages and limitations of new MRI techniques with Echo planar diffusion weighted (EPI-DW) and non Echo planar diffusion weighted (non EPI-DW) imaging.
