Doctor :   hi
Doctor :  
how can i help you
User :   Hi I have a few questions following a 19 week pregnancy ultrasound i recently had
Doctor :   ok

Doctor :  
kindly proceed with your query
User :   The ultrasound report reported that the baby has a retro-cerebellar cystic prominence most pronounced on the right side
Doctor :   ok

User :   what does all this mean/ possibly indicate?
Doctor :   is this your first child?

User :   no, second child
Doctor :  
it indicates certain malformations int he brain
Doctor :  
the malformation is seen behind the cerebellum
User :   the report went on to say that it is most likely simple anatomical variation as opposed to an acrachnoid cycst. Maximal sagittal diameter is 6mm - what is normal measurement?
Doctor :  
in the form of a cyst(fluid filled sac)
Doctor :   yes
Doctor :  
as i told you it is simple cyst found behind the cerebellum
Doctor :  
there is nothing to worry about it
User :   so if it was an arachnoid cyst, what would be the impact on the brain after birth?
Doctor :  
arachnoid cysts are true developmental anamolies
Doctor :  
they usually present in later in life
User :   so would a congenital cyst as this may be, impact at all on cognitive function at all?
Doctor :   it need not be necessary that it will cause cognitive dysfunctyion
User :   so the brain would function in a 'normal' manner? the child would have no cognitive disability?
Doctor :   yes

Doctor :  
there is nothing to worry
Doctor :  
they are variants of normal
User :   would you suggest a secondary level ultrasound for further investigation?
Doctor :   it should be followed up with the scans to find if the cyst increases in size

User :   And if it is a cyst that does increase in size, what would be the outcome?
Doctor :  
if the cyst is small and does not cause any efect it is not a problem
User :   But if it does increase in size, outcome?
Doctor :  
it may press on some important structure of brain
User :   can it be treated?
Doctor :  
it may some times cause hydrocephalus
User :   thankyou, much appreciated
Doctor :  
are you there
Doctor :   Please fill the feedback form say done.

Doctor :   Have you filled the feedback form?
Doctor :   Is there any thing else I can help you with?
Doctor :   are youthere
