The classic imaging features on CT scan for nonaccidental

0:05

trauma include subdural hematomas of various ages.

0:10

This is a series of reconstructions of axial CT scan

0:14

images in a patient who had nonaccidental child abuse.

0:19

What one can see are collections

0:22

that are of various densities,

0:25

overlying bilateral convexities.

0:28

Some of these are more acute

0:31

and some are old,

0:33

and some may be subacute in age.

0:38

As I said,

0:40

multiple subdural hematomas of different ages

0:42

are classic for nonaccidental trauma.

0:46

Another area that one can have extra-axial collections

0:49

that are typical of nonaccidental trauma,

0:51

but not specifically in this patient,

0:53

are along the interhemispheric fissure

0:55

that is unusual in a child

0:58

other than in the setting of child abuse.

1:01

You may also see multiple skull fractures of various ages

1:06

that can occur also in patients who

1:08

have undergone child abuse.

1:11

Here we have another example of a similar phenomenon

1:15

and that is the collections of blood of different ages.

1:19

One sees the higher-density collection,

1:22

an intermediate-density collection,

1:24

a low-density collection,

1:26

all in this one single scan,

1:29

as well as the interhemispheric hemorrhage

1:33

that is concerning for a patient who had

1:36

nonaccidental child abuse.

1:38

In this case,

1:39

the patient also showed evidence of retinal hemorrhages.
