Mariska Hargitay has been shifted to ER from the Special Victim’s Unit.

The Emmy-winner of NBC’s “Law & Order: Special Victim’s Unit” was hospitalized on Wednesday following a partially collapsed lung. The producers of the show had released a statement about her ailment in January this year though the exact nature of her ailment was not disclosed. She is reportedly undergoing tests at the hospital and may require more surgery.

Her spokesperson, Leslie Sloane confirmed that Mariska was back in hospital for the third time “after experiencing some discomfort relating to her earlier lung condition. She is undergoing routine tests and expects to be better soon.” Ms. Sloane also said that the production of the show will continue in spite of the setback.

According to reports Marissa was working on the sets for the show and moved to the hospital only ater she finished filming.

An injury to the lung may often be the cause for the formation of adhesions on the outer cover of the lung or pleura. These adhesions can snap because of physical activity and trigger off a spontaneous pneumothorax situation. Mariska was hospitalized for the first time in December after a sledding acident in the Hamptons and this was her third visit for pneumothorax.

Marissa Hargitay the 45-year old actress from the show first suffered the situation when the show was on holiday hiatus and the production was stalled temporarily till she recovered. She had been a Golden Globe nominee for her portrayal of Detective Olivia Benson but could not attend the Golden Globe or the Screen Actors Guild Awards. She did return the filming after two weeks but nothing was revealed about the severity of her condition.

Hargitay is now the highest paid television actress in the Guinness Book of World Records, 2008.
