She was only trying to save a parking spot — and now doctors are trying to save her life.

A petite young Bronx woman was pummeled into a coma by a thug who was furious that she was holding a parking space in the East Village, The Post has learned.

“She’s 25 years old. Her life was just starting, and it might be over,” said the woman’s mother, Angie.

“You have no idea how horrible this is and the senselessness that it was over a parking spot.”

Lana Rosas was holding the spot for her boyfriend between two parked cars outside 520 E. 14th St. at 11:40 p.m. last Friday when Oscar Fuller drove up in a silver minivan.

Fuller — whose prior busts include weapons possession and felony assault — jumped out and started screaming at Rosas when she claimed she was holding the space, police sources said.

Fuller then “punched [her] in the face with so much force that the woman flew off her feet,” according to court papers.

“She was on a date with the man she loves, and this horrific thing happen to her,” her mother said.

The victim’s uncle, Mark Rosas, fumed, “We have idiots out here who try to take matters into their own hands . . . Animals like that need to be caged up.”

A police source added, “The victim suffered permanent brain damage. It’s uncertain whether or not she will survive her injuries.”

Fuller, 35, allegedly sped from the scene, which is across the street from Stuyvesant Town, but cops got his plate number and two witnesses picked his mug from a photo array.

Detectives arrested him at his home on 195th Street in Jamaica, Queens, Tuesday night, and he was picked out of a lineup at the Ninth Precinct station house, sources said.

The electrician, a father of two, was charged with felony assault and remains jailed at the Manhattan Detention Center in lieu of $100,000 bail.

“I would never intend to physically hurt a woman,” he said in a statement through his lawyer, Thomas Kenniff.

“If there is anything I could do to strengthen her recovery, I would do it.”

The lawyer accused Rosas of starting the fight and insists surveillance video shows her throwing the first punch.

“She hit him in the face,” Kenniff said. “My client has the injuries to prove it.”

But a police source said Fuller admitted to punching a woman at the scene.

Rosas’ mother was outraged he would blame her daughter.

“So she was the aggressor? Really?” she asked. “She’s 4-foot-11. How is she the aggressor?

“It doesn’t matter what she said to him or what he said back. He hit her twice, and he hit her hard enough to shake her brain and make it blow up.”

Rosas remains at Bellevue Hospital, where doctors had opened her skull to relieve pressure on her brain.

At her Clinton Avenue apartment in the Tremont section, where she lives alone, the super described Rosas as a tiny beauty who weighs about 100 pounds.

Despite Fuller’s extensive arrest record dating to 1994, his lawyer and neighbors described him as a helpful family man.

“He is a beautiful father of a 4-year-old son and a 10-year-old daughter,” Kenniff said. “He’s a churchgoing man.”

Sidney Maloney, 60, said, “The other day, he helped me fix my lawnmower.”

“He said, ‘Sidney, what’s up with you?’ I told him, and he brought out his tools.”
