Mediastinal Lymphosarcoma in a Seven-Month Old Labrador Retriever

Abstract

Diana L Eubanks

A seven-month-old female spayed Labrador retriever was diagnosed with canine lymphosarcoma. The initial presenting sign was vomiting with a history of possible foreign body ingestion. Laboratory data revealed hypercalcemia and thoracic radiographs demonstrated a mediastinal mass. A diagnosis of mediastinal lymphosarcoma was based on thoracic radiographs and subsequent cytology of the mass. The case was managed with chemotherapy and nutrition. The dog improved for a brief period and was euthanized seven weeks after initial presentation due to disease progression and poor long-term prognosis. This case was unique considering the age of the dog involved.
