WASHINGTON--Secretary of State Hillary Rodham Clinton is being treated for a blood clot in her brain, her doctors said Monday.

The State Department issued a statement by her doctors, Dr. Lisa Bardack and Dr. Gigi El-Bayoumi who said Clinton did not suffer from a stroke and is being treated with blood thinners.

"This is a clot in the vein that is situated in the space between the brain and the skull behind the right ear," the doctors said.

The blood clot was discovered on Sunday, but the State Department did not reveal the location or other detailed information about the diagnosis.

Clinton remains hospitalized at the New York-Presbyterian Hospital.

Here is the full statement from Clinton's doctors:

"In the course of a routine follow-up MRI on Sunday, the scan revealed that a right transverse sinus venous thrombosis had formed. This is a clot in the vein that is situated in the space between the brain and the skull behind the right ear. It did not result in a stroke, or neurological damage.

"To help dissolve this clot, her medical team began treating the Secretary with blood thinners.

"She will be released once the medication dose has been established. In all other aspects of her recovery, the Secretary is making excellent progress and we are confident she will make a full recovery. She is in good spirits, engaging with her doctors, her family, and her staff."
