The Usefulness of Brain Magnetic Resonance Imaging with Mild Head Injury and the Negative Findings of Brain Computed Tomography
A 53-year-old woman visited our hospital because of headache after pedestrian traffic accident. She had past medical history of hypertension and not taken any other medications. At the time of admission, GCS score was 14 points, and she had loss of consciousness. She showed normal level of coagulation factor on routine hematology examination. Except for scalp laceration, external wound of the other head parts was not observed. Initial brain CT scan which was taken at other institution did not show abnormal lesion, except scalp swelling. She had continuous headache and dizziness for 3 days. Thus, we performed brain MRI which showed hemorrhagic contusion at left frontal lobe (). After we managed with medication and closed observation, she was discharged without any neurologic deficit 1 week later.
