체중 2.2 kg 4년령 수컷 Maltese 개가 호흡곤란과 고체온증 평가를 위해 건국대학교 부속 동물병원에 내원하였다. 신체 검사에서 호흡곤란을 확인 하였으며, 오른쪽 흉강 청진상에서 희미한 심음을 확인하였다. 방사선 검사와 CT검사에서 오른쪽 중간엽의 경화와 흉수 및 복수를 확인하였다. 탐색적 개흉술을 통해 $360^{circ}C$ 염전 된 오른쪽 중간엽을 확인하였으며 TA 장치를 이용 염전된 폐엽을 절제하였다. 복수 원인을 확인하기 위해 탐색적 개복술을 통한 소장생검을 실시하였으며, 조직 검사를 통해 림프관 확장증을 확인 하였다. 림프관 확장증 치료를 위해 prednisone과 저지방 사료를 사용하였으며, 임상증상의 개선을 확인하였다.
A 4-year-old intact male, Maltese dog weighing 2.2 kg was presented for evaluation of tachypnea and hyperthermia. On initial evaluation, the dog was dyspneic, but alert and responsive. Muffled heart sound was noted with auscultation of the right hemithorax. The radiographic findings were consolidation of the right middle lung lobe, pleural effusion, and abdominal fluid accumulation. Thoracic computed tomography confirmed a contrast-enhancing mass within the right middle lung lobe. Surgical exploration of the thoracic cavity was performed using a right fifth intercostal thoracotomy. Examination of the right lung lobe revealed $360^{circ}C$ torsion of the right middle lung lobe at the level of the hilus, in a clockwise direction. Lung lobectomy was performed using a thoracoabdominal stapling device with 2.5-mm vascular staples. Full-thickness intestinal biopsy by exploratory laparotomy was taken from the jejunum for histological assessment. Histopathologic examination of the full-thickness intestinal biopsy revealed distended lacteal located within the submucosa of the jejunum. Intestinal lymphangiectasia was resolved with prednisone and low fat diets. Subsequent communication with the owner revealed that the patient was in good health 6 months post-discharge.
