is unresponsiveAxial CT without contrast of the brain shows high density material in the subgaleal tissues posteriorly, a wide lucency in the right posterior skull along with two areas of depressed lucency in the left frontal skull, a rounded high-density lesion in the midline of the cerebellum, and decreased density of the cerebrum when compared to the normal density of the cerebellum along with loss of the normal gray matter-white matter differentiation.The diagnosis was a posterior subgaleal hematoma, a right posterior diastatic skull fracture and a left frontal depressed skull fracture, cerebellar contusion and diffuse cerebral edema in a child abuse patient.

Depressed skull fractures result in the bone of the skull vault being folded (depressed) inward into the cerebral parenchyma. It is usually the result of a high energy impact to the skull.

Pathology

These mostly (~75%) occur in the frontoparietal region .

Associations

There are a number of associated injuries with depressed skull fractures :

Radiographic features

Plain radiograph

Rarely undertaken, especially outside of the pediatric population. The fracture is identified due to the projection of dense bone over the skull.

CT

The modality of choice in head trauma. The fracture is shown in detail along with any associated injuries.

Treatment and prognosis

There are a number of indications for operative management, these include :

Depressed skull fracture are associated with higher rates of infection (~10%), seizure (~15%), neurological deficits, and death .
