Thymomas and mediastinal lymphomas are common types of tumors found in the chest area of cats, with lymphomas usually seen in younger cats and thymomas in older ones.
A unique case of a nearly 4-year-old male cat presented with exercise intolerance and breathing issues, leading to the discovery of a large mediastinal mass through imaging and biopsies.
After surgery to remove the mass, the cat was diagnosed with a thymoma and had a successful recovery, showing no further issues in follow-up exams after 8 months.
