Bone Scan BRAIN INFARCT
(Prepared by Dr I Berrocal)
Male 76 y/o, history of pain in several joints and diagnosed as RA. Underwent hip and knee phrosthesis surgery. Current hospitalization due to CVA. Note intense brain infarct uptake. In addition, intense increased uptake in wrists, small joints in both hands, shoulders, sternum synchondrosis, around hip and knee prosthesis, ankles and left tarsus. Bladder catheter and reservoir between legs.
It has been described phosphonate uptake in myocardial, spleen and brain infarct due to calcium deposit in weeks following the occlusion. In this particular case it is clear that the lesion is in the brain and correlates with recent CVA. In smaller lesions in could be mistaken by a skull process.
