AB Extra-axial  fluid  collections  in  children  are  classified  as  symptomatic  and  asymptomatic.  Symptomatic,  chronic  extra-axial  fluid  collections  have  been  variously  classified  as  hematomas,  effusions,  or  hygromas  with  differing  definitions  associated  with  each.  It  has  been  proposed  that  they  all  be  classified  together  as  extra-axial  fluid  collections  because  their  appearance  on  CT  scan  and  the  treatment  is  identical.1  Symptomatic,  chronic  extra-axial  fluid  collections  usually  show  ventricular  compression  and  flattening  or  obliteration  of  the  cerebral  sulci  on  CT  scans.  Benign  subdural  fluid  collections  usually  appear  as  a  hypodensity  over  the  frontal  lobes  with  dilatation  of  the  interhemispheric  fissure,  cortical  sulci,  and  Sylvian  fissure.  The  ventricles  are  usually  normal  or  slightly  enlarged  with  no  evidence  of  transependymal  flow.
