Gliomatosis cerebri (infiltrative diffuse astrocytosis) is a rare primary brain tumor. It is commonly characterized by diffuse infiltration of the brain with neoplastic glial cells that affect various areas of the cerebral lobes.〔(Gliomatosis Cerebri, MedPix : 923 - Medical Image Database and Atlas )〕 These malignancies consist of infiltrative threads that spread quickly and deeply into the surrounding brain tissue, or into multiple parts of the brain simultaneously, making them very difficult to remove with surgery or treat with radiation. 〔(About Gliomatosis Cerebri )〕 Gliomatosis cerebi behaves like a malignant tumor that is very similar to Glioblastoma. While gliomatosis cerebri can occur at any age, it is generally found in the third and fourth decades of life. ==Presentation== It may affect any part of the brain or even the spinal cord, optic nerve and compact white matter. Clinical manifestations are indefinite, and include headache, seizures, visual disturbances, corticospinal tract deficits, lethargy, and dementia. A case of gliomatosis cerebri presenting as rapidly progressive dementia and Parkinson's disease like symptoms has been described in an 82-year-old woman.〔http://jmedicalcasereports.com〕
