A woman suffering from a stroke was allegedly injected with soup.

Ilda Vitor Maciel of Rio de Janeiro died Sept. 28 at the age of 88 and her family alleges the death was caused when one of the nursing technicians injected soup into the woman’s vein instead of her feeding tube, according to HispanicallySpeakingNews.com.

The family is now filing a lawsuit against Santa Casa de Barra Mansa, the hospital where Maciel was admitted after she had a stroke in late September. She died 12 hours after the injection.

"When she injected into a vein, my mother began to beat. I got scared and called the nurse," Maciel's daughter, Ana Ruth Maciel dos Santos, told the Brazilian newspaper Globo.

Hospital officials acknowledge that Maciel was injected with soup by mistake but they don't believe that's what caused her death, according to the Brazilian news website GezetaPovo.com.br.

However, the information sheet signed by a doctor at the hospital lists "pulmonary embolism" as the probable cause of death. which, according to SidneyRezende.com, would support the family's claim that the soup injection killed Maciel. A pulmonary embolism is a blood clot on the lung.

An investigation into the matter has begun and should be completed within 30 days, according to KHQ.com.
