Early Diagnosis of Posterior Cranial Fossa Tumors

  • Aldo Fortuna


In relation to the small dimensions of the posterior cranial fossa, a tumor can cause blockage of the cerebrospinal fluid and various other symptoms in an early stage. Headache is localized in the suboccipital region with nuchal and neck irradiation or with frontal region irradiation and is often associated with vomiting. In the early stage, vomiting is projectile in character and is not associated with headache. The vomiting occurs mainly in tumors of the fourth ventricle because of the direct compression on the bulbar centers of the vagus.
