My husband has been getting a CT scan every month since his m/c accident 3/9/2011. It is possible, like in his case, to develop CSF (Cereobral Spinal Fluid) in the frontal lobe where there was an injury to the brain or shift (my understanding). A month later, the CSF was absorbed by the body but because there was still a small empty space a vessel ruptured and left a small bleed. His neurosurgeon decided to monitor it ...

His next appointment is June 24, 2011 with a more recent CT scan on the 23rd.
