Young man falls from a second story window. Arrives somnolent but will awaken to voice. Multiple episodes of nausea and vomiting.
The images:
Small parenchymal bleed.
The classic radiographic appearance of an epidural hematoma. The neurosurgeon took him to the operating room for a decompressive craniotomy.
