Cut the sausage into thin slices. In a large skillet, saute the sausage slices until crispy and browned around the edges. Add the garlic just as the sausage is browning, and cook for about 1 minute. Add the cream and Cajun seasoning to the skillet with the sausage, stirring until the seasoning and cream are blended.
Bring the cream mixture to a boil, then reduce heat and simmer for 3-4 minutes, until the cream mixture starts the thicken.
Remove the pan from the heat and stir in the parmesan. Add the pasta to the pan and toss to coat. Serve immediately.
** Heavy Cream can be substituted for whipping cream
