Abstract
A 13-year-old, female, mixed-breed dog with a huge cranial mediastinal mass underwent
radiotherapy (RT). On the following day, the dog presented with lethargy and anorexia.
Hematological examination revealed elevated levels of blood urea nitrogen, creatinine,
inorganic phosphorus, potassium, lactate dehydrogenase, creatine phosphokinase and
aspartate aminotransferase, decreased calcium level, and metabolic acidosis. Urine output
markedly decreased. The patient recovered with fluid therapy and diuretic therapy;
however, died suddenly from an unknown cause 11 days after RT completion.
Histopathological examination after necropsy showed thymoma in the cranial mediastinum and
extensive tubular necrosis of both kidneys which may be due to RT-induced tumor lysis
syndrome (TLS). This report suggests that the risk of TLS should be evaluated in dogs with
thymoma who undergo RT.
