A report by the Los Angeles County Medical Examiner stated on Thursday that Lisa Marie Presley's death in January was caused by a "sequelae of a small bowel obstruction."

A small bowel obstruction is a blockage in the small intestine, often because of things like scar tissue, a hernia or cancer. Without surgery, it can cause bowel tissue to die or perforate, leading to death.

Lisa Marie, the only daughter of the late Elvis Presley and Priscilla Presley, died hours after being hospitalized following an apparent cardiac arrest on January 13.

She was 54.

LA County Fire Department spokesperson Kaitlyn Aldana had told CNN that emergency responders were dispatched to a call in the 5000 block of Normandy Dr in Agoura Hills, California, at 10:37am local time for a cardiac arrest. Aldana would not confirm the name of the the patient, who could not be identified due to privacy laws, but said the patient was taken to a to a local hospital at 11:17am.

A spokesperson for the LA County Sheriff told CNN they assisted fire officials on a medical call this morning, but also would not confirm the patient's name.

"Priscilla Presley and the Presley family are shocked and devastated by the tragic death of their beloved Lisa Marie," Priscilla said in the statement, provided to CNN by a representative at the time. "They are profoundly grateful for the support, love and prayers of everyone, and ask for privacy during this very difficult time."

Lisa Marie's last public appearance before her death was at the Golden Globe Awards, which she attended with her mother to support the Baz Luhrmann film "Elvis," about her late father.
