My husband has been seeing several dr's trying to find the cause of all his symptoms. The main ones being nausea, unintentional weight loss of 50lbs and fatique. They all suspected a cancer of some form but were unable to find it. We finally asked that a pet scan be done and it showed calcifications in his brain. Does this mean he has brain cancer? He has daily headaches but nothing like a migraine. His symptoms seemed to be more gastro but I looked up symptoms for brain cancer and they are there. His dr is in the process of scheduling him for a mri of his brain. He is 42. Anyone know what calcification in the brain means?

  • The MRI will give you a more definitive diagnosis. Calcifications do not necessarily mean malignancy. Of note, the PET scan is not a reliable source of evaluation of the brain. The PET scan measures glucose activity in the body after drinking the glucose soluton prior to the scan. The brain has the highest glucose metabolic uptake in the body prior to the scan, so the scan is not very effective in evaluating "abnormal" uptake. The PET scan does a great job of showing abnormal "activity" in general areas & are effective with certain diagnoses, but is not great in defining specific anatomical areas. CT's & MRI's do a better job of locating abnormalities in certain anatomical areas. They are best used in conjunction with each other. - Rod

  • Thank you for taking time to respond. He did have the MRI's with and without contrast. They followed them with a ct scan because it beter detects calcifications in the brain. A large dense calcification was found within his pineal gland. The mri's made note of alot of sinus issues and sinus cancer was suspected. Further testing rulled that out. He is now suffering from several neurological symptoms.
