AB  - Extra-axial  fluid  collections  are  described  as  fluid  collection  that  are  external  to  the  brain  parenchyma.  These  include  epidural  hematomas,  subdural  hematomas,  and  subarachnoid  hemorrhages.  Intra-axial  fluid  collections  develop  within  the  brain  parenchyma.  Extra-axial  fluid  collections  in  children  are  classified  as  symptomatic  and  asymptomatic.  Symptomatic  extra-axial  fluid  collections  have  been  classified  as  effusions,  hematomas,  or  hygromas.  Their  appearance  on  computed  tomography  (CT)  scans  and  the  treatment  for  each  are  identical  (Figure  149-1).1  CT  scan  images  of  symptomatic  extra-axial  fluid  collections  usually  demonstrate  ventricular  compression  and  flattening  or  obliteration  of  the  cerebral  sulci  on  CT  scans  (Figure  149-1).  Asymptomatic  or  benign  subdural  fluid  collections  usually  appear  as  a  hypodensity  over  the  frontal  lobes  with  dilation  of  the  cortical  sulci,  interhemispheric  fissure,  and  Sylvian  fissure.  The  ventricles  are  usually  normal  in  size  or  slightly  enlarged  with  no  evidence  of  transependymal  flow.
