Traumatic
aneurysm is known to be very rare
vascular disease. The authors experienced one case of traumatic
aneurysm that occured on pericallosal
artery after
closed head injury. Traumatic
aneurysm was suspected by enlarged traumatic ICH on the
corpus callosum in
brain CT scan and presence of signal voiding at the center of the
hematoma in
brain MRI scan and then confirmed by transfermoral carotid
angiography. Clipped
neck of this traumatic
aneurysm successfully via interhemispheric approach, we
report a case of traumatic pericallosal
artery aneurysm with
review of
literatures.
