Case Discussion

Following the eustachian tube in CT scans can be difficult as it is not always patent along its entire length. However, if the patient were to perform a valsalva manoevre, this space would likely open up and become easily visible.

In this particular scan the patient is not performing such a manoevre, but the path is still visible.
