Mohamed Eleiwa, a spokesman for the Egyptian Prisons Authority, said the examination was routine and that the 84-year-old former leader's health has been good recently, the Middle East News Agency reported.
Gulf News said the Egyptian newspaper al-Masry al-Youm had reported Tuesday that Mubarak had suffered minor injuries when he fell in a prison bathroom.
Mubarak, who is being held in the Tora prison hospital, was reported to have been in seriously deteriorating health in June.
Mubarak was ousted from the presidency last year. This year, he was sentenced to life in prison after being convicted of corruption.
