Spontaneous reduction of growth rate of a large intracranial meningioma. Case report.

A relatively young patient with a large intracranial meningioma producing a paucity of neurological signs and symptoms showed no progression of symptomatology over 14 years. This may represent a spontaneous growth arrest in an otherwise early expected fatal outcome. The location of the tumor with its benign course producing no demonstrable increase in visual loss over 14 years in such a young patient is quite unusual.
