Tiger Woods’ former mistress Rachel Uchitel will undergo brain surgery later this month, TMZ reported.

Uchitel will go under the knife in mid-September, according to the gossip site, in an effort to treat Chiari (kee-AH-ree), a condition in which brain tissue extends into the spinal canal, pressing on the brain and forcing it downward, according to the Mayo Clinic website.

Uchitel’s doctors reportedly will cut into the back of her head and attempt to lift her brain out of the spinal canal. About 50 percent of patients who undergo the surgery become symptom-free, according to TMZ.

After her affair with Woods was revealed, Uchitel went on to marry former Penn State football player Matt Hahn. The couple had a daughter in 2012, and finalized their divorce last year, according to the New York Daily News.
