An unprecedented case of penetrating head trauma caused by shoji (a Japanese-style paper sliding door)

Abstract

Penetrating head trauma (PHT) includes any traumatic injury where an object pierces the skull and breaches the dural membrane surrounding the brain. PHTs are less prevalent than blunt head injuries. However, they often have more complex damage, worse prognosis, and higher rates of morbidity and mortality. An 83-year-old man fell at his home and hit his head on the right side toward a shoji (a Japanese-style paper sliding door). He reported to the emergency room the following day with his family. He had a small wound before the right ear, which was sutured in the emergency room. A CT scan demonstrated tiny pieces of bone fragments inside the brain, as well as right temporal subcortical hemorrhage and pneumocephalus. He was admitted to the hospital and received intensive prophylaxis with antibiotics. He developed life-threatening skin disease and subsequent acute kidney disease requiring hemodialysis. He fully recovered from his life-threatening condition. Here, we report an unprecedented case of a penetrating head injury of an older adult caused by a shoji.
