Large posterior fossa tumor centered in the fourth ventricle and extending out of the left foramen of Luschka. It extends anterior to the brainstem and also just into the left IAM.
Case Discussion
This tumor is centered on the fourth ventricle and extends out of the ventricular system via the foramen of Luschka. The main bulk of disease is extra-ventricular with extension anterior to the brainstem and into the internal acoustic meatus on the left.
Posterior fossa tumors in children consist of four main entities. As classically described, the ependymoma is the tumor that will exude from foramina in an almost plastic fashion, much akin to toothpaste being squeezed from a tube.
