Magnetic Resonance Imaging and Pathological Findings in a Cat with Brain Contusions

Abstract

Necropsy was performed on a mongrel male cat of unknown age weighing 1.3 kg, which probably encountered a traffic accident. Gross pathological examination of the brain revealed reddish colour of the right cerebral hemisphere and haemorrhages on the surface of the right frontal lobe to temporal lobe. Histologically, there was diffuse vacuolation in the cortex of the right frontal lobe and extensive haemorrhages in the base of brain. These histopathological findings were consistent with areas of abnormal signals found on post-mortem magnetic resonance imaging (MRI). In this study, the MRI findings were identical to that reported in human cases of head trauma as well as histopathological changes.

Head trauma in the feline patient – an update

“…This is supported by research showing that the histological changes (and magnetic resonance imaging changes) in a cat brain were identical to those in humans, (Sato et al, ).…”
