easy · MCQ · Q-9B65A9
A 28-year-old male is brought to the emergency department following a high-speed motor vehicle collision. He was unconscious at the scene, briefly regained consciousness ('lucid interval'), and then rapidly deteriorated into a coma with right-sided hemiparesis and a fixed, dilated left pupil. Which of the following vessels is most likely injured?
- A.Middle meningeal arteryCorrect answer
- B.Bridging veins
- C.Anterior cerebral artery
- D.Vertebral artery
Solution
The classic presentation of a lucid interval followed by rapid neurological deterioration (coma, ipsilateral pupillary dilatation due to uncal herniation, and contralateral hemiparesis) is characteristic of an epidural hematoma, most commonly caused by a tear of the middle meningeal artery secondary to a temporal bone fracture.
