1How is PCNSL diagnosed?

Common symptoms that would be cause for further investigations:

  1. Severe headaches of increasing frequency.
  2. Visual distortions.
  3. Balance issues.
  4. Constant ringing in the ears (Tinnitus).
  5. Unexplained changes in mood or attitude.
  6. Slower/poorer thinking and memory skills.
  7. Tremors or seizures.
  8. Troubles with speech.
  9. Extreme (bed soaking) Night sweats.

Occasionally experiencing any one of the above symptoms does not mean you have a serious condition.  If you have two or more of these symptoms with increasingly frequency to should contact your Primary Care Physician for further tests.
Frequently used initial diagnostic methods include:

  1. Ability to track with both eyes.
  2. Equally reactive pupils.
  3. Equal hearing in both ears.
  4. Equal sense of touch at various points of the body.
  5. Equal reflexes in arms, legs, and feet.
  6. Equal strength in arms, shoulders, and legs.

More advanced Diagnostic tests frequently used to detect a tumor are:

  1. A computed tomography (CT) -  uses X-rays to make detailed pictures of structures inside of the body.
  2. Magnetic resonance imaging (MRI) - An MRI machine can produce high definition 3D images.

It is not possible to accurately and positively the nature of a suspect mass without some form of biopsy.  Depending on the size and location of the mass a minimally invasive “needle biopsy” might be an option other cases may require more significant surgery  to obtain a proper tissue sample for pathology testing. There are several significant markers that will distinguish PCNSL from other types of brain tumors (Astrocytomas, Gliomas, Oligodendrogliomas, etc.  Only a pathological exam of the tissue can accurately determined.  Accurate diagnosis is the most critical step to starting a treatment program!  It is not uncommon for people to have and initial diagnoses of a Glioblastoma Multiforme the most frequent and most deadly form of brain cancer. Only a tissue biopsy will offer an accurate diagnosis!
