Atretic occipital lipoencephalocele in an 18-year-old female. (A, B) Axial T2WI and T1WI showing both T1- and T2-hyperintense mass (*) in the occipital region with herniation of CSF, meninges and atretic brain parenchyma (black arrow) through a defect in the occipital bone. (C) Sagittal T1WI fat-saturated post-gadolinium image showing suppression of fat component of the mass (white arrow). (D) is a 3D TOF SPGR image in the venous phase showing no communication of the mass with the cerebral venous system.

There was a large mass showing both T1- and T2-hyperintense signal area suggestive of fat component (Figure 1).
Atretic occipital lipoencephalocele in an 18-year-old female. (A) Sagittal reformatted CT image in a bone window showing a defect in the occipital bone (black arrow) and (B) showing Y-shaped bony outgrowth from the occipital bone (hollow arrow). (C) Axial image in a modified window showing a fat-density mass (F), encephalocele (white arrow) and bony component (hollow arrow). (D) is a coronal reformatted bone window image showing a fat-density mass (F), encephalocele (white arrow) and bony component (hollow arrow).

There was a Y-shaped bony outgrowth seen arising from the occipital bone into the mass (Figure 2) which was quite unusual in association with an atretic lipoencephalocele.
