The head ct results have come back, and here is what they show: there is no sign of tumor, bleeding, or skull trauma. in fact, the only abnormality is that the ventricles are slightly smaller than normal. drag each piece of data to the hypothesis it rules out.

It may be safe to say that we can rule out a concussion for this patient. The CT scan is negative for trauma to the skull, brain bleed and negative for tumors. However, there is a slight abnormality regarding the smaller size of the ventricles but otherwise unremarkable.
