Pope Francis has made a quick trip to a hospital for tests and returned to the Vatican, two months after he was hospitalized with an acute case of bronchitis

The checkup comes after Francis was admitted to the hospital for a bronchial infection on March 29 and discharged on April 1. Francis' health has raised concerns as he has been seen requiring a wheelchair during a state visit to South Sudan and at public events.

Because his check-up was on Tuesday, a day on which he normally does not have any audiences in the Vatican, it seems reasonable to say the visit was scheduled in advance.

Pope Francis went to Rome's Gemelli hospital for a brief check-up on Tuesday and has returned to the Vatican, the Holy See's press office said in a statement.

According to Italian news agency ANSA, the pope entered the hospital at 10:40 a.m. for a visit to the hospital’s geriatric medical center. He reportedly left the hospital at 11:20 a.m. to return to the Vatican.
