Tardieu's spots are subpleural and subepicardial petechiae classically associated with death by:
- A Mechanical asphyxia ✓
- B Carbon monoxide poisoning
- C Cyanide poisoning
- D Electrocution
Correct answer: A. Mechanical asphyxia
Explanation
Tardieu's spots are pinpoint haemorrhages seen under the pleura, pericardium, and conjunctiva as a result of increased venous pressure and capillary rupture during mechanical asphyxia. They were described by Tardieu and are characteristic of asphyxial deaths such as strangulation, smothering, and traumatic asphyxia, though they can also occur in other conditions with raised venous pressure.
