[Foreign body in the orbital cone: case report]. / Corpo estranho no cone orbitário: relato de caso.

Orbital injuries may be associated with the presence of foreign bodies in which long retention leads to damages such as loss of vision or cerebral abscess. We present the case of a 21-year-old male patient that developed ptosis, limitation of movements and an inflammatory reaction in the right eye after being hit by a tree branch. A CT scan of the orbits revealed an increased density in the right orbital cone. After the neurosurgical approach for the removal of the foreign body, a wooden fragment measuring 2.0x0.3 cm, the patient had a good outcome without visual deficits, ptosis regression and resolution of the inflammatory process. The postoperative CT scan didn't identify any remaining foreign body fragment. This case calls attention to the fact that the wooden splinter presented on CT scan with high density (136 HU) two months after the trauma and was removed by a supraorbital craniotomy.
