Pope Francis has for the first time appointed a woman to a high post in the administration of the Vatican City State.
She is the first woman to hold the second highest office in the governorate.
She will oversee the Vatican Museums and other Vatican State services such as the Currency and Stamp Office and the Fleet.
Petrinie, 52, from Rome was with the Congregation for the Evangelization of Peoples, which does missionary work.
Francis has focused on women in his staffing decisions in recent months.
Earlier in the year, he made theologian Nathalie Becquart the first woman in the history of the Catholic Church to serve as undersecretary of the Synod of Bishops.
Then, in August, Francis appointed Sister Alessandra Smerilli Acting Secretary of the Dicastery for the Promotion of Integral Human Development, which focuses on issues of migration and poverty.
She was also appointed delegate of the Vatican Covid-19 Commission.
