Ms Fernandez, 60, was undergoing medical checks for another condition when the bleeding - a subdural hematoma（硬脑膜下血肿） - was discovered.

 

Vice-President Amado Boudou is flying back from France to take over her duties. 

 

Ms Fernandez has been campaigning ahead of congressional elections. 

 

The break from campaigning is considered awkward（尴尬的，笨拙的） for the president as some opinion polls have suggested the government could lose control of Congress in the poll on 27 October. 

 

Her spokesman, Alfredo Scoccimarro, issued a statement saying her doctors had carried out a brain scan in August after a previously¹ undisclosed trauma² - thought to be caused by a fall. 

 

However, they found nothing untoward³. 

 

On Saturday, she went to hospital for checks for an irregular heartbeat and also complained of headaches. 

 

A further scan revealed the subdural hematoma - bleeding between the brain and the skull⁴. 

 

The condition is said to be "chronic⁵" but not "acute" according to the presidential statement, and Ms Fernandez will not be staying in hospital. 

 

Her doctors are to monitor the bleeding using imaging technology. 

 

President Fernandez, a centre-left Peronist, was first elected in 2007 and then returned to power by a comfortable majority in 2011. 

 

There have been hints that she may seek a third term, though she has never confirmed this. 

 

This would also require a change to the constitution - only possible if her party keeps control of Congress.
