Abstract

An 18-month-old intact male Pomeranian dog was presented because of traumatic head injury from a fall. Based on physical and neurological examination, brain injury was suspected. On plain skull radiographs, bony fragment following fracture was identified in the region of the right occipital bone. On computed tomography (CT) images, there were specific findings associated with an intracranial hemorrhage. The patient expired few hours after diagnosis, and performed necropsy. On gross findings, intracerebral hemorrhage and edema was detected and those were consistent with CT images. This report describes the clinical findings, CT imaging characteristics, necropsy findings, and histopathologic features of severe traumatic brain injury in a dog.

18년 령의 수컷 포메라니언견이 낙상으로 인한 외상성 머리 손상으로 내원하였다. 신체검사 및 신경검사 후 뇌손상이 의심되었다. 두부 방사선 쵤영에서 우측 후두골 부위에 골절로 인한 뼈조각이 관찰되었다. 전산화 단층촬영상에서 두개 내 출혈 소견이 확인되었다. 두부 외상에 대한 처치에도 불구하고 환자는 내원 수 시간 후 폐사하였고 부검을 실시하였다. 육안 검사 상 대뇌 피질의 출혈 소견과 부종이 확인되었으며 이는 전산화 단층 촬영 결과와 일치하였다. 본 증례보고는 개에서 발생한 심한 외상성 뇌손상의 임상적 특성, 전산화 단층촬영 영상적 특징, 부검 소견, 그리고 조직학적 변화를 잘 보여주고 있다.
