Final answer:
Shotgun pellet embolism is the appearance of streaks extending from lead pellets in the nasal cavity. It is a life-threatening condition that requires immediate medical attention.
Step-by-step explanation:
The appearance of steaks extending from the lead pellets in the nasal cavity is called shotgun pellet embolism.
Shotgun pellet embolism occurs when the lead pellets from a shotgun blast become fragmented and travel through the bloodstream to different parts of the body. In this case, the pellets have traveled to the nasal cavity and are causing streaks.
This condition can be life-threatening and requires immediate medical attention. Treatment usually involves surgical removal of the pellets and repair of any damage caused.
