Scary moment for Olympic gold medalist Sofia Goggia ... the alpine skier banged her head and busted her leg during a violent crash at the World Cup on Sunday -- just weeks before she's supposed to defend her title at the winter games in Beijing.
Luckily for Goggia, the injuries aren't catastrophic.
The frightening incident was caught on video ... showing the 29-year-old going full speed down hill at Cortina d'Ampezzo Super G event.
Everything appeared normal until the Italian skier lost control on a turn .
