Traumatic aneurysm from shaken baby syndrome: case report.

OBJECTIVE AND IMPORTANCE

We present a 6-week-old infant who developed a traumatic aneurysm from clearly documented shaken baby syndrome. Despite the theoretical similarity in the mechanism of such injuries, this is the first aneurysm reported that resulted from such a cause. The infant is also the youngest reported patient to have suffered from a traumatic aneurysm.

CLINICAL PRESENTATION

Police records documented shaking of the child as well as direct impact on the child's head. Three weeks later, the patient developed an intracerebral hemorrhage, which was revealed by angiography to have resulted from a pericallosal artery aneurysm.

TECHNIQUE

The aneurysm was totally resected through a porencephalic cyst, which had developed secondary to ischemic injury to the brain.

CONCLUSION

The temporal course, as well as the location of this traumatic aneurysm, is similar to that in older patients.
