초록

11살 수컷 페키니즈가 10일간의 발작을 주증으로 내원하였다. 내원 15일전 파행으로 지역병원에서 소염제를 처방 받았었고 10일 전 간헐적 전신발작을 시작으로 내원 2일 전에는 실조와 정신둔감이 함께 발생하였다. 혈액검사와 영상학적 검사상 특이소견은 관찰되지 않았으나, 신경계 검사상 위협반사와 동공 빛 반사가 떨어짐을 확인할 수 있었다. 내원 9시간 후 호흡곤란이 발생하였고 그 후 12시간 후 보호자의 요청으로 안락사를 실시하였다. 부검상 가로 단면에서 확장된 종양으로 인해 현저한 중심선 이동을 관찰할 수 있었다. 조직학적 분석을 통해 신경아교세포의 거짓 울타리화된 괴사와 미세혈관의 증식을 확인할 수 있었다. 면역염색 결과 종양 부위에서 GFAP, PCNA, Iba-a 에 염색된 세포가 관찰되었다. 이와 같은 결과를 바탕으로 아교모세포종으로 진단되었다. 원발성 두강내 종양은 수의학에서 흔하지 않다. 이번 증례는 페키니즈견에서 아교모세포종의 임상적, 조직학적 발견에 대한 보고이다.

An 11-year-old, intact male Pekingese was brought to the Veterinary Teaching Hospital of Kangwon National University with a 10-day history of seizures. Fifteen days before coming to Kangwon National University, the dog had visited a local animal hospital for lameness, and non-steroidal anti-inflammatory drugs were prescribed to treat this symptom. However, 10 days before coming to our hospital, the dog experienced generalized seizures. Two days before his arrival, generalized ataxia and mental dullness also occurred. Our examinations revealed no remarkable findings on a routine blood test or X-ray. However, the neurological examinations confirmed mental dullness, generalized ataxia, and a lack of menace response and pupillary light reflexes. Nine hours later, dyspnea occurred, and 12 hours after that, the patient was euthanized per the client's request. A necropsy of transverse sections confirmed the presence of a prominent midline shift due to extended tumor growth. On histopathological analyses, pseudopalisading necrosis of the glial cells and microvascular proliferation were observed. In immunohistochemical analysis, glial fibrillary acidic protein, proliferating cell nuclear antigens, and ionized calcium binding adaptor molecule 1 immunoreactive cells were observed in the tumor area. Based on the results, the tumor was confirmed to be a glioblastoma. Primary intracranial tumors are rare in the veterinary field. This case report describes the clinical and histopathological findings of glioblastoma in a Pekingese.
