Figure 2: Child Occipital Encephalocele. Encephaloceles may be quite large, but the parenchyma within the encephalocele should be similar in its signal intensity to normal brain parenchyma as demonstrated on axial FLAIR (top row left) and T1 (top row right – axial, bottom row – sagittal). The size of the calvarial defect, thickness of the encephalocele pedicle, and involved intracranial structures can be clearly seen on MRI. Variable amounts of CSF may be seen in the protruding defect. Very little CSF is present in this encephalocele.
