Pilocytic astrocytoma

Common Name(s)

Pilocytic astrocytoma

Pilocytic astrocytoma is an often benign, slow-growing tumor of the brain or spinal cord. The tumor may be in the form of a cyst and usually does not spread to nearby tissues. Symptoms vary depending upon the size and location of the tumor. Most symptoms result from increased pressure on the brain and include headaches, nausea, vomiting, balance problems, and vision abnormalities. The underlying cause of a pilocytic astrocytoma is unknown. It most commonly occurs in children and young adults, and in people with neurofibromatosis type 1 (NF1), Li-Fraumeni syndrome, and tuberous sclerosis. This type of tumor can often be cured with surgery.

Dysembryoplastic neuroepithelial tumor-like pilocytic astrocytoma: A case report.
 

Author(s): Jia-Ming Liao, Wei Wang, Jing Xie, Hai-Bo Wu

Journal: Medicine (Baltimore). 2018 May;97(20):e10755.

 

Pilocytic astrocytoma (PA) typically shows biphasic pattern with a mixture of loose microcystic and compact regions, in which it is not uncommon to see heterogeneous morphology. However, there has not been reported in the literatures of the PA type that shows similarity to dysembryoplastic ...
