Plain-English summary

A dog developed serious breathing and neurological problems six days after being rescued from a fire. The symptoms included progressive neurological issues, which were linked to damage in the brain caused by smoke inhalation. Unfortunately, the dog did not survive, and a post-mortem examination revealed significant brain damage. This case highlights the potential for delayed neurological symptoms in pets exposed to smoke.

Abstract

Acute respiratory and neurologic disease after smoke inhalation are well documented, but human patients may also develop delayed-onset neurologic symptoms associated with leukoencephalomalacia after exposure to smoke or carbon monoxide. In this case, a dog developed progressive neurologic signs 6 days after rescue from an apartment fire. At necropsy 9 days after smoke inhalation, leukoencephalomalacia of the central cerebral white matter was accompanied by laminar necrosis of cerebrocortical neurons. This is the first report of delayed posthypoxic leukoencephalopathy in a nonhuman animal.
