To assist in diagnosing chardoma, doctors combine information from symptoms, family history, a physical exam and specialized tests.
Screening for chardoma usually starts with a neurological exam to evaluate movement, hearing, speech, reflexes, balance and coordination, behavior and mental state. Some of these tests must be performed by specialists. The doctor may elect to extract a small amount of tissue from the tumor for a biopsy to verify that it is cancerous and ascertain the best treatment option.
Diagnostic imaging such as computed tomography (CT) scan and magnetic resonance imaging (MRI) provide highly detailed views of the body and tumor. Other imaging tests for chardoma use variations of this technology sometimes including special dyes and radioisotopes that provide exacting details of affected areas.
Additional tests for chardoma may include:
- laboratory tests of blood, urine and other bodily fluids
- electroencephalogram (EEG)
- analysis of the spinal fluid
- magnetoencephalography (MEG) which measures the brain’s electrical activity
