  Intractable worsening headaches, severe nausea/vomiting, dizziness, vertigo, and neck stiffness are all possible symptoms. Chemical meningitis is usually self-limiting and may be treated with steroids if necessary. [neurosurgicalatlas.com]

  It is quite rare that it actually produces vertigo because the slow growth permits ample time for compensation. These tumors are resectable, though larger tumors may leave residual deficit. [dartmouth.edu]

• Hyperreflexia

  Tumors of the brainstem region may be associated with gaze palsy, multiple cranial nerve palsies, and upper motor neuron deficits (e.g., hemiparesis, hyperreflexia, clonus). [obgynkey.com]

  They may develop macrocephaly, hyperreflexia and cranial nerve palsies. Children with an intracranial tumour and neurofibromatosis: Reduced visual acuity, exophthalmia and optic atrophy. [patient.info]

“Prognosis” refers to the probable course and outcome of the disease. Physicians reference one or more clinical studies to obtain their prognosis statistics. [cern-foundation.org]

On the whole, the long term prognosis is better in children than adults. Incidence The incidence of pediatric brain tumors is roughly 3.3 cases per 100,000 children in North America. [pedsoncologyeducation.com]

However, there are different opinions among doctors about importance of grade in determining the prognosis for children diagnosed with grade II ependymoma or anaplastic ependymoma (WHO grade III). [cancer.net]
