Fossa of Rosenmüller

The fossa of Rosenmüller, also known as the posterolateral recess, is the most common site of origin for nasopharyngeal carcinoma.

It is located superior and posterior to the torus tubarius (the posterior projection of the cartilaginous portion of the eustachian tube), and is formed by mucosal reflection over the longus colli muscle.

The fossa of Rosenmüller appears posterior to the ostium of the eustachian tube on axial images and superior to the ostium of the eustachian tube on coronal images.
