OBJECTIVE AND IMPORTANCE: We present a 6-week-old infant who developed
a traumatic aneurysm from clearly documented shaken baby syndrome. De
spite the theoretical similarity in the mechanism of such injuries, th
is 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 s
haking of the child as well as direct impact on the child's head. Thre
e weeks later, the patient developed an intracerebral hemorrhage, whic
h was revealed by angiography to have resulted from a pericallosal art
ery aneurysm. TECHNIQUE: The aneurysm was totally resected through a p
orencephalic cyst, which had developed secondary to ischemic injury to
the brain. CONCLUSION: The temporal course, as well as the location o
f this traumatic aneurysm, is similar to that in older patients.
