Diagnosis and Management of Pericardial Mesothelioma in a Leopard Gecko (Eublepharus macularius).

A 17-year-old male intact leopard gecko (Eublepharus macularius) was presented for lethargy, distended abdomen, and rapid weight loss. Palpation revealed ascites and subcutaneous edema in the axillary region bilaterally. Coelomic ultrasonography revealed a large (19 × 14 × 14 mm), focal, irregularly marginated heterogeneous cavitated mass associated with the right side of the heart.
