A few days later the patient presented at an emergency hospital with bruising on the abdomen. On physical examination there were ecchymotic hemorrhages over the entire ventral abdomen extending up to the right axilla; tetraparesis associated with right front limb lameness with decreased postural reactions and reflexes; and mild hyperpathia upon manipulation of the cervical spinal column. PCV/TP was stable between 26-28%, 4DX test was negative, abdominal ultrasound showed no evidence of active bleeding, and thoracic radiographs were negative for effusion and metastatic disease. Follow up physical examination several days later was predominantly unchanged, although the ecchymotic hemorrhages were resolving. The current medications were continued. Three days later the patient was presented on emergency with lethargy, weakness, distended abdomen, and tachypnea. On physical examination the patient was lethargic, weak, tachypneic, tachycardic, non-ambulatory on front right forelimb and there were new ecchymoses on the left caudoventral abdomen. Mucous membranes and heart and lungs were all normal. PCV/TP was 17/5.2. The patient was treated with Benadryl and was transfused with packed red blood cells and fresh frozen plasma. The following day patient was QAR, eating well, and eupneic. Due to poor prognosis and no hope of improvement of quality of life, owner’s elected to euthanize. On postmortem a primary compound osteosarcoma of soft tissue of the brachial plexus with liver metastasis was diagnosed.
