L'Express magazine on Tuesday reported the contents of a medical file from the woman's first hospital examination in New York shortly after the May 14 incident.
"Cause of the injuries: assault. Rape," the report said, according to the French translation in L'Express.
A lawyer representing the accuser said the report proves the attack occurred.
But defense lawyers for Strauss-Kahn criticized her team for releasing the report, calling it "misleading and deceitful" because it was based almost entirely on her account.
Nafissatou Diallo, 32, a hotel maid from Guinea, alleged Strauss-Kahn, 62, emerged naked from the bathroom of his luxury suite at the Sofitel hotel on May 14 and sexually assaulted her -- charges that Strauss-Kahn has vehemently denied. He is formally charged with attempted rape and sexual assault.
The report described Diallo's hospital examination when, "in tears," she told doctors at New York's St. Luke's Roosevelt Hospital that a man grabbed her crotch forcefully, leaving red marks on her vagina, and forced her to perform oral sex. The struggle also injured her shoulder, L'Express said.
Reuters could not confirm the medical report because Diallo's lawyer, Kenneth Thompson, was unable to make it immediately available. But Thompson said the report proves the attack occurred and belies the suggestion by Strauss-Kahn's defense team that any sexual encounter was consensual.
"The medical records are pretty powerful," he said. "Forensics don't lie. That's the bottom line."
But Benjamin Brafman and William Taylor, Strauss-Kahn's attorneys, said in a statement that using the medical reports was "misleading and deceitful." Moreover, they said the report confirms that the accuser did not have any injury caused by a forcible encounter.
