How Do You Diagnose Astrocytoma?
Astrocytomas are tumors of the central nervous system primarily derived from an astrocyte (large neurolgia cell.) These tumors are divided into two classes: those narrow zones of infiltration and those with diffuse zones of infiltration. There are also various grading systems of astrocytomas based on their histopathology. The World Health Organization system is widely accepted and recognizes four grades. The following steps will show how to diagnose astrocytomas. Observe the neurological symptoms caused by an astrocytoma. These can vary widely based on its size and location but can include cognitive and motor impairment, headaches, seizures and sensory anomalies. Examine the patient neurologically to determine the extent and location of the astrocytoma. This is essential because these tumors can affect any part of the central nervous system including the spinal cord and may spread to distant regions. Perform a Magnetic Resonance Imaging (MRI) scan with and without contrast as the diagn
