The unusual radiologic presentation of an optic chiasm fibrillary astrocytoma extending through and expanding the diaphragma sellae in an 8-year-old male is described. The child presented with decreased vision in the right eye. [ncbi.nlm.nih.gov]

The most common presenting feature ( 40% of cases) is seizures. This is particularly the case in adults. Headaches are often also present. [radiopaedia.org]

Detection of many of the molecular changes that underlie the development of gliomas and other BT can now be done by immunohistochemistry and is getting into the mainstream of the diagnostic workup of BT. [neuropathology-web.org]

Treatment[edit] Treatment options include surgery, radiotherapy, radiosurgery, and chemotherapy. [en.wikipedia.org]

Treatment Treatment is controversial. Some tumors may be observed with serial MRI with the assumption that almost all of these tumors will at some point undergo malignant degeneration to a higher grade tumor. [prod.wiki.cns.org]

/ Standard of Care Treatment options depends on the overall health of the person, the type, size, and location of the tumour, if and how far it has spread and previous treatment received. [braintumour.ca]

Our findings emphasize the individuality of PA as a distinct clinicopathologic entity with an exceptional prognosis. [ncbi.nlm.nih.gov]

Prognosis A prognosis is an estimate of the likely progress of a disease after a diagnosis, based on an average patient group. [braintumour.ca]

Complete surgical excision of low-grade tumors is associated with a good prognosis. However, the tumor may recur if the resection is incomplete, in which case further surgery or the use of other therapies may be required. [en.wikipedia.org]
