Feb. 18 (UPI) -- Pope Francis has developed pneumonia in both lungs as he remained hospitalized Tuesday in Rome, according to the Vatican, which called the 88-year-old's condition "complex."
"The follow-up chest CT scan which the Holy Father underwent this afternoon ... demonstrated the onset of bilateral pneumonia, which required additional drug therapy," the Vatican said, adding that the pope's lab tests, chest x-ray and condition "continue to present a complex clinical picture that will require an adequate hospital stay."
