History: A 7 year old intact male Llama had a 3 day history of lethargy, decreased water intake and oliguria. The Llama was febrile with increased lung sounds (R>L). A CBC showed leukocytosis and pre-renal azotemia. An ultrasound showed consolidated tissue in the right thorax.
The mediastinal lymph nodes were enlarged. A large soft white mass (lymph node) measuring 15 cm x 3 cm x 3 cm was found beneath the vertebral column in the thorax.
The abdomen contained approximately 1L of clear yellow fluid.
The liver contained multifocal 3 mm to 15 mm white nodules that were slightly raised above the liver capsule and found throughout the liver parenchyma.
A large white infiltrative mass was present in the wall of C3 which caused a 20 cm round area of ulceration and necrosis of the mucosa of C3. The mass was adhered to C1 and the liver. The contents of C3 contained partially digested blood.
The kidneys both had multifocal 3 mm -10 mm white nodules.
The gross lesions are consistent with lymphoma, which is pretty common in Llamas.
The immunohistochemistry did not stain well. I am having them redone.
The thorax contained approximately 1 L of yellow to orange clear fluid with a small amount of fibrin.
The lungs were cranioventrally consolidated and purple in color. This was diagnosed as bacterial bronchopneumonia.
