CT scan:

1. Diffuse soft tissue swelling of loose connective layer of
   scalp, compatible with caput succedaneum. (Fig.1)
2. Focal crescent high attenuation fluid fixed to left parietal bone,
   may due to small subdural or epidural hematoma. (Fig.2) 
3. Much fluid accumulation in loose areolar layer of scalp,
   in favor of subgaleal hematoma. (Fig.3,4)
4. Focal crescent high attenuation fluid in subperiosteal space of
   left parietal bone, in favor of extracranial cephalohematoma. (Fig.3,4)

MRI (2weeks later):
1. Focal crescent intermediate short T1 fluid in subperiosteal
   space of left parietal bone, suggesting extracranial
   cephalohematoma. (Fig.5)
2. Some short T1 fluid accumulation in loose areolar layer of scalp,
    in favor of subgaleal hematoma. (Fig.5)
3. A 1.2x0.5x0.4cm small long T2 lesion in anterior portion
   of left parietal subcortical region, in favor of encephalomalacia
   from previous brain injury. (Fig.6)
