Noncardiogenic pulmonary edema: a certain etiology?

An emergency paramedic call finds a 40-year-old woman unresponsive on the floor with shallow respiration, pink froth and vomitus about the mouth, pulse 36, blood pressure 136 by palpation. She had been cleaning in her kitchen and common household chemicals were open nearby. On arrival in the Emergency Department, a chest X-ray showed bilateral pulmonary infiltrates consistent with pulmonary edema. Heart size normal. Despite all efforts, the woman died. Post mortem examination revealed ruptured cerebral vascular malformation as the cause of death.
