Perforating eyelid injury extending to the brain stem in a 17-year-old woman: a case report.
BACKGROUND
This case report describes a patient who had a perforating eyelid injury that extended to the brain stem.


METHODS
A 17-year-old Japanese woman complained of decreased vision in her right eye, with severe ocular pain and headaches, after the metal tip of an umbrella struck her upper right eyelid accidentally. Her vision in the right eye decreased to light perception with commotio retinae, intraretinal hemorrhage, and severe lid swelling. Magnetic resonance imaging (MRI) demonstrated edema of the head of the caudate nucleus and putamen, and the edema extended to the hypothalamus. The MRI findings indicated that the umbrella tip had penetrated through the eyelid and the posterior orbital wall. Vision improved to 20/50 in the right eye, with subretinal fibrosis caused by the choroidal rupture.


CONCLUSIONS
We recommend that MRI be performed on the orbit and brain in patients who appear to have symptoms that are inconsistent with the observed injury and when a severe orbitocranial injury is suspected.
