Hillary Clinton's blood clot an uncommon complication

(AP) - The kind of blood clot in the skull that doctors say Mrs Hillary Clinton has is relatively uncommon but can occur after an injury like the fall and concussion the secretary of state was endured earlier this month.

Doctors said on Monday that an MRI scan revealed a clot in a vein in the space between the brain and the skull behind Mrs Clinton's right ear.

The clot did not lead to a stroke or neurological damage and is being treated with blood thinners, and she will be released once the proper dose is worked out, her doctors said in a statement.

Mrs Clinton has been at New York-Presbyterian Hospital since Sunday, when the clot was diagnosed during what the doctors called a routine follow-up exam. At the time, her spokesman would not say where the clot was located, leading to speculation it was another leg clot like the one she suffered behind her right knee in 1998.
