Weapon injuries other than gunshot wounds or low-velocity stab wounds to th
e head are extremely rare. We report the case of a 6-year-old girl who sust
ained a penetrating craniocerebral injury after being accidentally shot wit
h an underwater fishing harpoon. This mechanism of injury seems to share ch
aracteristics of both high- and low-velocity projectiles. We discuss the ma
nagement of this unusual injury in a child, remarking that foreign body rem
oval in these cases must be carried out following the original direction of
the projectile trajectory. We review the current literature on craniocereb
ral injuries caused by similar objects, especially those occurring in child
ren.
