Post-mortem computed tomography angiography and forensic necropsy of a brown howler monkey: A case report

The purpose of this case report was to compare, in a brown howler monkey (Alouatta guariba clamitans), the findings of the post-mortem computed tomography (PMCT) with the forensic necropsy, and also to describe a successful post-mortem computed tomography angiography (PMCTA) study. Post mortem CT images revealed two thyroid cartilage fractures that were not seen at the forensic necropsy. The PMCTA was a feasible technique, but did not change the final diagnosis in this case. The PMCT findings were considered crucial to determine the cause of the disability of the animal, and this disability was believed to contribute to the cause of death. In conclusion, PMCT added relevant information to the establishment of the final diagnosis, and can be considered an important adjuvant tool to the veterinary pathology.
