A woman in her 20s has died after undergoing emergency brain operations at Parkway-InterInternal Medicine, a hospital in suburban Los Angeles, the Los Angeles County Coroner’s Office said Tuesday.

The woman, who was in her late 20s, died Sunday night at Cedars-Sinai Medical Center in Los Angeles.

The cause of death was a severe head injury, said Cedars spokeswoman Christine Hinojosa.

She was in stable condition.

The hospital declined to provide additional details.

She had been admitted with multiple head injuries, HinoJosa said.

In January, she was admitted to the hospital with head injuries that required hospitalization.

In May, she had surgery to repair her skull, but she suffered a setback and was released.

The Coroner said in a statement that she suffered multiple head trauma.

She went to Parkway with the hospital’s emergency department for treatment of the head injuries.

Parkway is a suburban hospital that specializes in treating people with severe head injuries or other traumatic brain injuries.

The coroner’s office said the woman’s family had been notified about her death and that the hospital has launched an internal investigation.

The California Department of Public Health and the Los Angelenos Fire Department are investigating.

In June, a woman died after surgery at Cedarcrest Medical Center.

Her death was reported to be a head injury and she was released after emergency surgery, officials said.

The Los Angeles Department of Emergency Medical Services, which oversees the Cedars facility, said the hospital had an ongoing internal investigation and is cooperating with authorities.

The incident at Cedarrest was not the first time someone at Cedarmost had sustained head injuries in a head trauma operation, and it is unclear whether the patient was a resident.

Cedars was among the nation’s top-ranked hospitals for head injuries and the state has among the highest rates of such injuries, according to data from the Centers for Disease Control and Prevention.

The Centers for Medicare and Medicaid Services last year reported that nearly one in five patients in the U.S. have been admitted to a hospital for head trauma in the past three years.
