Context: One of the primary criticismes of vestibular schwannoma (VS) radiosurgery is that the risk of surgical morbidity is increased for patients whose tumor progresses after the procedures. We reviewed the French experience of operated patients after failed Gamma Knife radiosurgery. From July 1992 to January 2002, 25 out of the 1000 treated patients underwent another treatment procedure for a gamma knife failure. Excluding the NF2 patients, 21 patients have been operated and the present study shows the data collected for 20 of them. In order to analyze the difficulties observed during the surgery, a questionnaire was filled by the surgeons. The mean interval between radiosurgery and removal was 36 Months, from 10 to 83 Months. The mean increase in Volume was 559% (37 to 3036%, median 160%). Evolution of the Koos grading was found from 8 grade II, 10 grade III et 2 grade IV to 10 grade III and 10 grade IV. Patients have been operated for radiological tumor growth in 7 cases and for clinico-radiological evolution in 13 cases. In 9 cases, the surgeon considered that he had to face unusual difficulties mainly because of adhesion of the tumor to neurovascular structures. Tumor removal was total in 14 cases, near total in 4 cases and subtotal in 2 cases. One case of venous infarction was noticed at the second day following surgery responsible of hemiparesis and aphasia that gradually recovered. At last follow-up examination, facial nerve was normal (House and Brackmann grade I and II) in 10 cases while it was a grade III in 7 cases and grade IV and V in 3 cases. We recommend that the decision for surgical removal of growing vestibular schwannoma after Gamma Knife treatment should be done after a sufficiently long follow-up period. Our results show that the quality of removal and of facial nerve preservation might be impaired by radiosurgery in half of cases. However these results do not support a change in our policy of radiosurgical treatment of small to medium size vestibular schwannoma.

Context: The movie opens with James Reece (Jonathan Rhys Meyers) driving through the streets of Paris in a black SUV to work. Reece works in the American Embassy as an aide to Ambassador Bennington (Richard Durden), the U.S. Ambassador to France. Taking a delivery of some forms from the Ambassador's secretary, he goes over Bennington's itinerary for the next few days, centering around a major summit in which the U.S., France, and several other nations are preparing foreign aid to the African continent. Bennington shows that he is more absorbed right now in a chess game he's playing with Reece during all this time. Despite paying less attention to the board and the game than Bennington is, Reece quickly checkmates him to win.Reece receives a call from an unknown source (voiced by David Gasman) directing him to a silver BMW in the parking lot, excusing himself with a cover story to Bennington that he has to review the Summit's planned seating arrangement. Going to the parking lot, Reece opens a code-locked security compartment in the trunk of his SUV to reveal a firearm and several French license plates. He removes the license plate from the silver BMW and replaces it with one of the plates he has stowed away in his SUV. He then moves his SUV to another parking space and waits there, watching the silver BMW. He watches several men get into the vehicle, put a briefcase into its trunk, and drive away.Arriving home, Reece gets another call from the same source. Reece is in fact a CIA operative working in the Embassy as a cover. He does minor jobs for his superiors, and is eager to move up into Special Ops. His superior assures him he'll get his chance, but for right now he is needed to secure a hidden transmission chip in the French Foreign Minister's office during a meeting with Ambassador Bennington. Reece doesn't believe he was given a chip, but is told it's in his left jacket pocket. Checking his jacket, he finds the chip there.Sitting in his apartment, Reece examines the chip. He is interrupted by a knock on his door. It's his girlfriend, Caroline (Kasia Smutnak) (pronounced Cah-roll-een, the 'ine' being pronounced like in the word 'magazine'). Caroline kisses Reece and tells him she has a surprise. She sits him in a chair and makes him keep his back to her. He can hear her undressing and changing into a different outfit. When she tells him to look, his jaw drops at the sight of her wearing a sexy strapless dress. He thinks he recognizes the fabric, and Caroline tells him she made it out of their bedroom curtains-- Caroline is a clothing designer. The two of them quickly start to undress as they head into the bedroom to make out.Reece arrives the next day at the conference site to give Bennington a summary of what is intended to be discussed at the meeting. Bennington invites Reece to attend the meeting with him.During the meeting, Reece discreetly takes the chip (disguising it by putting a piece of gum in his mouth and offering another piece to the Minister's secretary) and tries to put it under the lampstand beside his seat, using his chewing gum as an adhesive. However, the gum fails to hold and twice it falls back to the floor in plain sight. Frustrated, and barely managing to keep the chip hidden, as a diversion Reece finally questions the Foreign Minister (Eric Godon) about his having several Goyas in his office. The Minister says he does, and offers to show them to Bennington, who is very interested in Goya art. As Bennington accompanies the Minister and secretary to see the Goyas, leaving Reece alone in the meeting room, Reece takes the stapler from the Minister's desk and staples the chip to the underside of the desk... but accidentally leaves the stapler open as he exits.Arriving home that evening, Reece is disquieted as the lights in the hallway go out. He finds what looks like a trail of blood leading to a door out onto the roof of the building. Grabbing a broom left in
