Primary cranial mediastinal hemangiosarcoma ina young dog Hun-Young Yoon1*, Hye-Mi Kang2 and Mi-Young Lee3 1Department of Veterinary Surgery, College of Veterinary Medicine, Konkuk University, Seoul 143-701, South Korea Full list of author information is available at the end of the article Primary cranial mediastinal hemangiosarcomas are uncommon tumors. A 30-kg, 2-year-old, intact female German shepherd was presented for evaluation of cachexia and respiratory distress of a few days’ duration. Lateral radiographic projection of the thorax revealed significant pleural effusion. Computed tomography revealed a cranial mediastinal mass effect adjacent to the heart. On surgical exploration, a pedunculated mass attached to the esophagus, trachea, brachiocephalic trunk, left subclavian artery and cranial vena cava without attachment to the right atrium and auricular appendage was removed and debrided by use of blunt dissection and dry gauzes, respectively. abstract Primary cranial mediastinal hemangiosarcomas 颅脑原发性纵隔血管肉瘤 cachexia 瘦弱，萎靡不振 respiratory distress 呼吸窘迫 Lateral radiographic projection 横向射线投影 thorax胸部 pleural effusion胸腔积液 Computed tomography 计算机断层扫描 cranial mediastinal mass 前纵隔肿块 pedunculated mass 带蒂肿块 esophagus 食管 trachea 气管 brachiocephalic trunk 头臂干 left subclavian artery左锁骨下动脉 cranial vena cava颅腔静脉 right atrium 右心房 auricular appendage 心耳 debrided 清除 blunt dissection钝性剥离 dry gauzes干纱布 New words Abstract Histopathology results described the cranial mediastinal mass as hemangiosarcoma. At 8 months and 5 days post-operatively, the patient died. Primary cranial mediastinal hemangiosarcomas, although a seemingly rare cause of thoracic pathology in young dogs, should be considered in the differential diagnosis for pleural effusion and soft tissue mass effect in the cranial mediastinum. This is the first case report in a dog to describe primary cranial mediastinal hemangiosarcoma. 组织病理学说 Case presentation A 30-kg,
