In summary, what emerges from this study is the clear delineation of two subtypes of posterior fossa ependymomaone with a predilection for younger children and associated with high mortality and morbidity and the other arising in both children and adults with better prognosisthat can be efficiently identified using standard and widely.
Most childhood ependymomas are found in the hindbrain (also called the posterior fossa), which controls functions like balance, movement, breathing and blood pressure. There are four different types of ependymoma, so you might hear your childs doctor call the brain tumour by a more specific name.
Infratentorial (posterior fossa) ependymomas in children, approximately 65 to 75 of ependymomas arise in the posterior fossa. Children with posterior fossa ependymomas may present with signs and symptoms of obstructive hydrocephalus caused by obstruction at the level of the fourth ventricle.
An ependymoma is a rare type of primary brain or spinal cord tumors. Ependymomas are found throughout the central nervous system in the supratentorial (top of the head), posterior fossa (back of the head) and spinal compartments. They are thought to develop from certain cells that normally mature.
Posterior fossa ependymomas in adults share many imaging features with pediatric tumors. The typical ct appearance is a mass filling the fourth ventricle, which is isodense or hypodense,.
Here, the authors identify predictors of functional outcome following microsurgical resection of adult posterior fossa ependymomas. Methods the authors identified adult patients with newly diagnosed who grade ii posterior fossa ependymomas who underwent microsurgical resection at the barrow neurological institute from 1990 to 2011.
In adults, the most common expansile mass lesion in the posterior fossa is a subacute stroke, whereas the most common neoplastic lesion in the posterior fossa is cerebellar metastasis (intra-axial) or vestibular schwannoma (extra-axial). Those diseases fall outside the scope of this article, which focuses on primary intra-axial tumors of the posterior fossa in adults.
