Feline Cystic Thymoma


Vanessa Barrs

Feline and canine thymomas are rare neoplasms of thymic epithelial cells, and the cancer more likely affects middle aged or older dogs and cats. Thymomas may be encapsulated and contained, or occasionally may spread by invasion and metastasis.
Surgical removal of cystic thymomas may result in long-term survival. Radiation and chemotherapy may be of value for advanced cases.

The thymoma was several times bigger than the heart! However, the mass was benign and the cat made a complete recovery.
