Argentine President Cristina Fernandez's doctors have ordered her to rest for a month after they found a hematoma in a membrane in her brain, her spokesman Alfredo Scoccimarro said.
The hematoma was linked to an August incident in which the 60-year-old president sustained a head injury, Xinhua quoted the spokesman as saying.
The president's thyroid glands was removed last year after she was diagnosed with cancer.
But soon after the surgery, it was announced that no cancer was present as postoperative tests showed no presence of any cancerous cells in the tissue of Fernandez's thyroid gland.
