CHIEF COMPLAINT: , Altered mental status.,HISTORY OF PRESENT ILLNESS: , This is a 6-year-old white male, who was sent from the Emergency Room with the diagnosis of intracranial bleeding.  The patient was found by the 8-year-old sister in the bathroom.  He was laying down on one side, and he was crying and moaning.  The sibling went and told the parents.  The parents rushed to the bathroom, they found him crying, and he was not moving the left side of his body.  He was initially alert, but his alertness diminished.  They decided to take him to the emergency room in Hospital, where a CT was done on his head, which showed a 4 x 4 x 2.5 cm bleed.  The emergency physician called our emergency room, and I decided to involve Neurosurgery, Mr. X, the physician assistant, who is on call for the Neurosurgery Services.  Collectively, they have made arrangements with the ICU attendings to have the child transported to our emergency room.  For a small stop, I am obtaining an MRI and then admitting to the ICU.
