The posterior fossa is a common site of oncologic disease in children, comprising at least one-half of tumors in children under the age of 10.63 Glial neoplasms of varying grade, medulloblastoma, and ependymoma are the most common diagnoses encountered. Despite the small volume of the posterior fossa, tumors may occur in a variety of locations, including the cerebellar hemispheres, fourth ventricle, brainstem, or the surrounding cisterns (Figure 6.7). Suboccipital, park bench, lateral, and sitting positions can be utilized based on patient pathology and surgeon preference. Dural opening, whether lateral or midline, is performed in close proximity to the dural venous sinuses, and carries the potential risk for significant blood loss. Infants and toddlers have additional risk for blood loss related to the frequent presence of an occipital sinus in this age group.64

The occipital sinus, is the smallest dural venous sinus, and communicates superiorly with the confluence of sinuses (torcular herophili) and inferiorly with the posterior internal vertebral plexus and receives tributaries from the cerebellum and medulla and drains the choroid plexus of the fourth ventricle.3
