1. Whisk together cream cheese and next 3 ingredients in a large bowl; stir in chicken, pineapple, and cranberries just until blended.
2. If desired, spoon mixture into a plastic wrap-lined 8-inch round cake pan; cover and chill at least 8 hours or up to 24 hours. Invert chicken salad onto a cake stand, and remove plastic wrap. Gently press chopped almonds onto sides of chicken salad. Garnish, if desired.
