[|Human|] My father in laws last CT scan results show as follows: No midline shift, Mild parenchymal volume loss is present. Encephalomalacia is seen in left frontal pole. Volume loss in Cerebellar hemisphere is seen. No mass, acute infarc, hemorrhage or extra-axial fluid collection. Bilateral frontal and parietal bur holes noted. Visualized portions of orbits and sinuses are normal. Mastoids are aerated. He suffered three subdural hematomas in December of 2012 and this report is the most recent (2014) ct scan.... what does it mean?
[|AI|]  Hello. I have been through your question and understand your concern. Overall this is a normal CT scan. The burr holes are due to the evacuation of the subdural hematomas. The cerebellar and cerebral volume loss is frequent finding after a certain age, generally after 65, but sometimes even earlier. It is considered physiological due to aging. Encephalomalacia in the left frontal pole is caused probably by what caused the subdural hematoma or the hematoma itself, but it should not cause any cognitive problem at this age. Again, you should not worry, because it is considered a normal CT scan. Hope this helps, please feel free for further questions.
