Objectives The aim of this study was to compare post-mortem CT findings with necropsy findings in domestic cats. Methods Post-mortem CT and necropsies were performed in 20 cadavers of domestic cats. The sensitivity, specificity and agreement between the post-mortem CT and necropsy findings were determined. Results There were a total of 315 post-mortem findings; 183 were identified by post-mortem CT and 132 were identified by necropsy. Post-mortem CT demonstrated a higher sensitivity to identify the findings mainly in bones. The higher indices of agreement between post-mortem CT and necropsy were related to abnormalities of pleural space, bones and joints. Conclusions and relevance This study demonstrated that post-mortem CT and necropsy provided different information. Thus, their use in conjunction with each other might improve the understanding of the cause of death and the identification of post-mortem lesions.

A descoberta dos raios-X por Wilhelm Roentgen em 1895 originou o campo da radiologia. O emprego de radiografias para o estudo em cadáveres foi introduzido em 1898 e utilizado durante décadas por patologistas. A virtopsia consiste na utilização de modalidades de imagem, tais como tomografia e angiotomografia computadorizada; ressonância magnética e técnicas minimamente invasivas como método complementar, triagem ou até mesmo substituição de autopsias convencionais. Em Medicina Veterinária, poucos artigos foram publicados a respeito e, portanto, apresenta uma perspectiva de estudos inovadores sobre o tema. Esta revisão de literatura tem por objetivo apresentar o cenário da tomografia e angiotomografia computadorizadas post mortem na Medicina e na Medicina Veterinária, contribuindo para a literatura sobre essa nova modalidade de interação entre o diagnóstico por imagem e a patologia.

Among the tumors affecting the choroid plexus in dogs, the papilloma ranks second place in incidence after cell carcinoma tumors. Presumptive diagnosis can be made through imaging methods, such as computed tomography and magnetic resonance images. Definitive diagnosis of plexus choroid tumor is based on histopathological findings. This report presented the tomographic features of the brain in a 6-year-old intact female Rottweiler with choroid plexus papilloma. The computed tomography showed right lateral ventricle enlargement, midline deviation and an enhanced mass into the postcontrast phase. At necropsy, a mass on the floor of the right lateral ventricle was observed, associated with important ventricle dilatation. The histopathological analysis demonstrated the presence of neoplastic cell forms with papillary projections. The computed tomography proved to be an effective tool in the presumptive diagnosis of this kind of cerebral disorder.
