Abstract:
Background: Falling from height is a common condition that can occur in different age groups.
Many types of injuries can occur due to it, such as skull fractures. Skull penetrating foreign bodies
(other than fire arm injuries and explosives) are generally uncommon. Penetrating blunt objects is
rare. CT is a useful modality in diagnosis of head trauma in general and in diagnosis of penetrating
foreign bodies especially. Unlike magnetic resonance imaging which is useful in special cases of
head trauma with a penetrating foreign body.
Case Report: We present a case in which a child presented at Sohag University hospital with falling
from a height less than 2 meters causing penetration of the frontal bone of the skull by a stone on the
land, which is a very rare presentation. The patient presented with scalp bleeding, post-concussion
and disturbed conscious level. Vital signs were normal. A Computed Tomography scan (Multislice
CT –8 slices) of the skull was done with 3D reformatted images.
Conclusion: Head trauma from penetrating objects (other than knife stapes or fire arm injuries) is
uncommon. Blunt object penetration is very uncommon. It can be serious or even fatal. CT is the
best imaging modality for diagnosis of such lesions. Metallic artifacts can be a limitation of their
role. Although the finding is almost diagnostic, still the history and clinical finding is the key for
diagnosis as the shape and density of the stone in some sections could be similar to ivory osteoma.
