Verdicts + Settlements

  • In May 2016, she obtained a settlement for a 67-year-old woman who sought care at a well-respected hospital’s emergency room for severe abdominal pain and constipation. The hospital administered an enema and a potent laxative without doing a necessary C/T scan. The woman was left with a perforated bowel, peritonitis, shock and loss of oxygen to the brain. The error required an emergency laparotomy, creation of a colostomy and left the woman with a permanent cognitive injury.

  • In April 2016, Ms. Walling settled a case involving the misdiagnosis of a 49-year-old wife and mother of four. A family doctor – who was not a radiologist — misinterpreted a chest x-ray and failed to see that the woman had developed lung cancer. As a result, the woman was left untreated and the cancer advanced to a non-curable Stage 4.

  • $3 million for a man who suffered brain injuries as a result of a failure of his physicians to timely diagnose a post-operative infection.

  • $1.875 million for the family of a 50-year-old woman, who died after becoming septic as a result of sound wave treatment for kidney stones.

  • $1.85 million for a 70-year-old woman who died after the doctors failed to provide proper treatment while she received a clot-busting drug.
